Things change, but YOU are still the same, even if life has affected you. I mean essentially you are always the same. Nothing as weak as time can change that. Nothing at all can change that. Also, I think "liking" you is different than being your friend. Yes certain things can affect if someone "likes" you or not, but if they are your friend, caring about you may be different than liking you superficially. If people don't care about you, but like you for something so superficial that it could change by the next time you see them, then F-them anyway.
