Someday soon you'll post a picture of your daughter as a teenager and that will make us all feel real old .

I'm in my 30s and people have always told me I look really young for my age. When I went back to school at uni, I'd be in classes with freshman and sophomores and the younger students could tell I wasn't one of them. Not everyone can tell my age, but some could and treated me accordingly (with distrust and aloofness). That made me feel old.
