I don't know how to react to certain situations that's why I keep mum. I am not a talker. I am socially awkward that's probably why I don't get along well with people because they think I'm aloof. I guess it has its perks? Now we have a better understanding of how you feel. I guess we are used to trying to lighten the mood or to comfort us because it is the "right" thing to do that's why we say those. It's like an automatic reflex.
