He was always a 4 kid.He wasn't the kind of boy who threw 5 at passing cars on a freezing winter day or who dropped water balloons on the mailman during the heat of August.

My oldest son wasn't perfect.He wasn't a math talent, either.But he knew what was important: he was focusing on his 19 while I was worrying over his past.And that, to me, is even better than being 20 . | ||||
