Does speaking less gets you less in trouble and conflict with people

First thing, you can't get close to someone if you never speak your mind. Closeness comes woth opening up and being vulnerable. Arguements happen in the best of relationships. Working through them in an honest non combative way is key. And absolutely possible if both want it to work. Sure, the more you know someone the more flaws you see. But accepting someone despite their flaws is at the root of love. And keep in mind you can have a healthy attachment to someone, or an unhealthy one.

There are going to be people out there looking for trouble no matter what.
Limiting one's interactions with others can at least minimize the chances of conflicts.

The drawback is that after so many years of socially isolating ones self, we pretty much forget how to even be friendly.

Not if I’m asking you a question it won’t.

Honestly, I tend to be more like the former and am described as someone who is hard to get to know and get close to (it's very hard for me to come out of my shell for people). Yes, it does spare me some drama and conflict I might otherwise experience, but at the same time, I have very few people I'm even b somewhat close to, and people have mistook me for being disinterested in them (which is not my intention at all). I'm getting better in this regard, but it's tough to break. I would say it comes with just as many costs as benefits.

While getting close to someone does allow you to see each other's flaws and usually results in the occasional disagreement, that's the price you pay for a close relationship. If it's a healthy relationship, it can be resolved and will not be something that ruins your friendship. Everyone who is close to someone experiences disagreements with them at some point, but they don't have to be the end of your relationship with that person, nor something that can't be worked through.

Honestly, I think there's a good middle ground. You obviously don't want to be too trusting and open with people you don't know very well, but you can gradually work up to that as you get to know them better. As for potential conflict, that's just something you'll have to decide for yourself is worth risking for a close relationship with someone or not.

Wow. The top half is actually a struggle for me. My whole family is too much for me. I don’t want anything to do with them. So yes, it’s normal. They’re not worth my time. And I’m alienating the fuck out of them. Normal.
