Worst quality? ...I'd have to go with my distinct lack of social skill in real life, I'm so shy that I find it hard to make new friends or feel comfortable around strangers.
Well that and I tend to judge anyone that upsets my mother very, very harshly even if I don't know both sides of the story. I really don't mean to, but I'm rather defensive of her so it happens without me even thinking about it.
In our little family the mama bear protects the baby bear and vice versa. xD
