It's a thing, and maybe only temporary, though I hope not. I don't know if it counts as a lesson either, but moving on, not dwelling on things(But at the same time not being naïve). That guy I kind of know who sort of beat me up? I swore to myself that I would stay mad at him and not be friendly anymore. 75% of that was gone the next day. Turns out he's a cool guy, a great friend, and just a confused teenager. It's completely by luck that this happens to me, but it does. It could be the difference between removing yourself from society and not having to be mad at at least one person 24/7.
