Questioning Her Mental Capacity

One of my students is now at university, and was telling me about another girl in one of her lectures. 

Girl: ... And she, just, like, constructed a fort from tables and chairs.  For no apparent reason.
Me: Why?
Girl: No idea.
Me: ... Does she do architecture? [no] Engineering? [no] So... why?
Girl: I have no idea.  But, we think she might have some... mental problems... I mean, she likes One Direction and Justin Bieber so I do question her mental capactity.

Five Husbands - Mental State

The girl who thinks I have five husbands looked at me, like she had a really serious question to ask me.

Girl: Um... Do you think I'm crazy?
Me: No.  You are very imaginative, though...
Girl: But do you think I'll end up in a mental... you know...?
Me: Mental asylum?  I doubt it.  But anyone can.  I think I would be more likely to end up in a mental asylum than you are.
Girl: Why?
Me: You know... the whole two lives thing... five husbands...?
Girl: But we both know that you do have five husbands.  And anyway, you have no feelings!
Me: Ouch!

I don't think she meant that in a mean way - it certainly didn't come across that way when she said it.  I would take it as a compliment, actually, in that I don't have very changeable moods as a teacher, but keep it a bit more professional.  Despite hearing all about my love life from an 11-yr-old.
