To really understand Sagittrius and Pisces relationships, you have to first understand which planets are in detriment in both signs. Both Sagittarius and Pisces are Mercury's detriment.

Both Sagittarius and Pisces think too much. Sagittarius, since it's also a fire sign, talks too much. They start off at point A and, by the time they finish talking, they're already at point F. Pisces doesn't have the reputation of running their mouth nearly as much but they should. Pisces likes to share a lot of random facts that are barely related to what you're talking about and it'll accidentally share what they're not supposed to all the time. Still, people seem to think of them as quiet people. I'm getting sidetracked.

The other thing that you have to understand about Sagittarius and Pisces is that they are both signs that dignify Jupiter.

I was once on a road trip, one that started off on a Mercury retrograde. During the trip, none of the five people who were on the trip could understand each other. People would say something at the back of the car and the people in the front would say, "What?" and get no answer. Someone would make a joke that someone else would mishear and they would spin off the mishearing.

But you know what? The miscommunication never caused any issues because all five of us took each other in good faith. We might not know what people are saying but we believed that they were saying something funny, smart, and kind so we would laugh along with everyone else even if we did not hear.

This is going to be similar to the dynamic between Sagittarius and Pisces. They both debilitate Mercury. Can they hear what the other person is saying? Not always or even usually. Both Sagittarius and Pisces hears words from the other one but it enters their mind as their own version of what the other person said. Both of them hear what they want to hear.

So, yes, miscommunication is strong between these two.

However, miscommunication is okay. If you take people in good faith, the friction of mishearing each other gets smoothed over.

Both Sagittarius and Pisces are people who like to look for the best in other people. If you say something hurtful, they'll truly believe that you didn't really mean it and will tell you what you really meant. If you say something critical, they truly believe that you're just trying to watch out for them. If you give them a compliment, they think that you're the kindest person to walk the earth and, if you say something smart, then they think you're the smartest person they have ever met.

Sagittarius and Pisces may not know what the other person is saying but they are taking one another in good faith. In fact, they think that the other person is the funniest person ever even if they didn't quite catch that last joke they told.

These are not people who try to catch you at your worst. Both Sagittarius and Pisces are people who soften any information that they receive using the power of their own minds. They have an intuition about the approximate shape of their partner in their minds but the details? The details seem to have gone missing.

So, yes, communication matters in a relationship. Sure. But Sagittarius and Pisces will never be the couple who gets the communicate-everything-with-perfect-clarity thing down. They make plans but neither of them know when to show up. They have expectations that they thought that they communicated well to the other person, Pisces with soft suggestions and Sagittarius with compliments, but it turns out that the other person didn't get the memo. They just thought that you were being nice.

Regardless, Sagittarius and Pisces can figure out a way. They might not know where and when to show up for a date but they're both available at some point. And they express their enthusiasm to see each other eagerly. They might have missed the memo about relationship expectations but they go out of their way to be good to each other.

Of course, this ability to gloss over miscommunication because both people believe the best about the other one can be a strength and a source of frustration.

As a strength, Sagittarius and Pisces believe in the other. They think that the other person can be a bit confusing but definitely a good person at the end of the day. They give each other the benefit of the doubt and they believe that everything will work out.

As a source of frustration, Sagittarius and Pisces can carry certain things that many people would communicate at the very beginning of a relationship years in. They're often shocked to learn that their partners doesn't, in fact, like it when they eat off their plate or doesn't want to have children the way they assumed they did. They often don't know where the other one is. Missed appointments, errands, and confused plans can make being a team hard.

Still, I do think that the positive aspects of Sagittarius and Pisces relationships outweigh the friction of miscommunication. These people could be married for ten years while having absolutely no idea where their partner lives. But they believe in their partner. They don't feel the need to keep track.

Even when Sagittarius and Pisces's plans go haywire, neither of them are put off. They're going to an event and miss the bus. "It'll all be okay in the end," Sagittarius comforts Pisces which Pisces mishears and says, "What? It's already ended? Oh, thank god. Now we can go home."
