That works better of course. For some reason half of lemmy is socially inept and assumes I would never ever leave a situation I find annoying or boring instead of like, finding a normal way to phrase it?

• oh well, guess I'll head out now
• see ya later
• I'm exhausted and need to go home
• I gotta leave, don't want to get home too late
• thanks for having me over

Or any variation that isn't outright rude to the other person works just fine. It isn't even about not signaling you're bored or whatever, just the blunt rudeness when there are plenty other options.

As for total dipshits who don't deserve better, why would you hang out in the first place?

That's me! People in my friend group know I have a social limit and can't always articulate things well. So it isn't uncommon for me to wander off mid conversation. About half the time with a "I'm heading out" and half the time I won't say anything, and everyone is cool with it
