I lost my cool points :(

Student: What was your name before you were married?
Me: [maiden name]
Student: Can I call you [maiden name]?
Me: Please don't, that hasn't been my name for almost 4 years.
Student: You've been married 4 years? And you don't have any kids yet? What's wrong with you? Do you even want kids?
Me: Not really, no.
Student: Wow, Ms. S--not cool. You are so not cool anymore.
Me: I didn't know I ever was cool.
Student: Uh, I don't know if you realize, but you just dissed yourself. Hard. *pauses* Seriously Ms. S, aren't you concerned about repopulating the earth?
