I have a new nickname at work... Little One. At first I didn't think it would stick, like so many of the previous ones. It actually works in two ways.

a) There are two Alex's at the store and I'm the younger/smaller one
b) I'm the newest full timer so I'll take this over rookie

and to be honest I kind of like this one. I don't mind responding to pages for Little One.

PS thanks Angie for the pictures of Chicago I used earlier
