Whatever, whatever, I do what I want

Exchange between me and my mom on New Years

Me: Ugh, that is a terrible credit card bill.
Mom: What the...are you spending all that money on itunes for?
Me: Well, Mom, I've really gotten into audio books.
Mom: What?
Me: You know, books on tape...but really as mp3s.
Mom: Where do you listen to them?
Me: Wherever I want!

I guess it's something that you had to be there for.
