One with a lot of love in it!
Nicknames to me is a sign of love and also respect.
My man calls me a varity of names, depending on his current mood (of course never anything bad), my colleagues also have a few names for me. And everyone get to have their own, I do not really care. The fact that they use the nicks, to me is a sign of friendship and developement in the relationship.
I have a pretty nickname-friendly surname so I'm used to be named a lot of things from people around me :)
