Because I want to

Before school today.....

Me: That's not your cardigan, it's huge!! Is that your sister's?

Her: Yes.

Me: Well do you want to go and get one of yours on?

Her: No.

Me: But it looks enormous on you, it doesn't fit!

Her: I know.

Me: Why are you wearing it?

Her: Because I want to.



And that short exchange sums up everything, right there.
