Unknown critical, or crit for short, is the best friend when it comes to needing a distraction, They Will manage to get you to think about pretty much anything else than the thing bothering you but they’re really bad at serious mental health stuff, as well as romance, they suck at romance. They love down talking themselves and gets mad at people of they say that they love crit. They’re the kind of friend that is so annoying but you love them too much to leave them.
