Talking to coseaters

I just don’t do it. Unless I’m on a flight to West Africa and want to practice my French, I’m a live and let live sort of person on a plane. I think it’s sort of weird to establish a bond with someone and then fall asleep right next to them. I’m also usually in the closest socially acceptable thing to pajamas while on a plane- it feels too intimate to make friends while in pajamas. I also don't want to be judged by someone I sort of know for the terrible movies I watch or for the way I explode the creamer all over myself multiple times in a flight. Anonymity is key.
