It's funny how you can see even at 5, what kind of teenager someone might become...
I walked into my bedroom (where the only full-length mirror in the house is) to find Anna posing in front of it in only her pants:
You know mummy, she ventured, I just can't wait till I grow up to be a teenager so I can wear the kind of clothes that don't fit!
I must have looked blank or at least surprised because she elaborated: You know, teenagers like to wear t-shirts that are too small for them so you can see their belly buttons! Oh my lord! This one is going to be a trendy little handful!
