That's a thing that will always happen in real life as well as online.
You've probably heard of the In ternet bullies...haven't you?
There will be people that can't stand you because of the way you are, that simple...and there will be people you won't be terribly fond of.
But well, life must go on and yes, you cannot please everyone.
There is a difference between "true friends" and "acquaintances". I've met both in this life.
How do you know? Sink the ship, the ones who jump out first, aren't your friends.
Take care.
