She has a strange sense of humor I think. For example she laughs when something bad or silly happen to someone else. Like, yesterday we went to ice skating and she was laughing of some kids falling or she even laughs when something painful happens to me.
She laughs of the pain of others or when they are in shame. Is normal? She also laugh of her friend because she speaks with a funny accent.
I mean I would laugh if somebody falls and it's funny but I would never laugh at little kids. Also laughing behind a friends back is a turn off. And also laughing at your SO is bad too. If he gets hurt I always say "aww it's ok baby" and I'll caress his boo boo or something
