I don’t know how to put it nicely, so I’ll say it as plainly as I can: it is an essential life todo item to learn to resist peer pressure. It’s easier than it seems. If people can get you to do things you don’t want to do just by repeating things at you, that’s a you problem, and a big one.

Also, separately, if the people you are hanging out with can’t take no for an answer, get better friends. Friends don’t pressure friends to poison themselves for camaraderie.
