You are starting to get the feeling that all of these girls are in cahoots. Are you in cahoots? Cahoots! You declare it and therefore they must recognize it. Cahoots! You feel really insecure about your new haircut. Friggin' cahoots, you say! This isn't a funny prank.
Holy fucking shit, ow! This hurts and you feel bad! You feel really bad! Physically and emotionally! Why would you do this happen?! Physically it hurts bad! Also your emotions! Was it because you complimented her hair? You guess it must be a point of insecurity for her, but it definitely does not merit lashing out to this extent.
