^^ My dad thinks I take things waaaay too seriously. I cry in movies, over books, sometimes even just touching chain emails.
I don't think they're meaning to say there's something wrong with you, just that they wouldn't cry over something like that. But as you can see, there are tons of people who are more sensitive to this kind of stuff.
Families usually criticize over a lot of stuff, I think it's meant more in fun than actually saying something is wrong. My brother and sister and I make fun of each other's clothes, music, food, the like. We never mean to hurt the other or say they have a problem, it's just what family does. ^^
