In which my little brother is not quite so little any more

Should I have stopped calling my younger brothers "little" when they could pick me up, when I had to start craning my neck to make eye contact, or can I still get away with "I'm your older sister, so obviously I know better!"? This post is to wish my 'little' bro Conrad a very happy 21st Birthday! He's had some big decisions going on in his life lately, and now what with being legal everywhere on the continent, I think he's going to be a busy, busy man in the coming year.

(sorry ladies...he is very, very taken, and I happen to like Sarah quite a lot)
