They grow up so fast, don't they?

This is my nephew Blake...he's 15 and taller than me. I remember when he was little...we were in the car for a while driving to Target (we lived in a really small town, so if you wanted Target, it was about 30-40 minutes away) and halfway there he was complainging about his legs hurting. Then he started crying. He was probably 3 years old... So we get to Target and I take him in the bathroom to find out what's wrong and I pull down his pants and his underpants...and there was another pair of underpants on. And another. And another. I was laughing hysterically at this point and asked what the deal was. He replied "Mommy bought me new Superman underwear and I couldn't decide which pair to wear today!" So he wore the whole package. Nerd. But man...it was like, yesterday...and now he likes girls instead of Superman underwear. Wherever does the time go?!?!?!?!
