Is It Learned, Or Are We Born With It?

Conversation between my son, 14 and my daughter, 12, while watching my daughter's favorite singer on American Idol.

Daughter: Who are those girls?
Son: What girls?
Daughter: Those girls from the audience, all around Colton.
Son: (Sighs) I feel sorry for your boyfriend.
Daughter: I don't have a boyfriend.
Son: Well when you do; I feel sorry for him.
Daughter: Why?
Son: Because you're so insecure.

Ugh.
