I don't as a rule like nicknames that much. Almost always, I'll like a long name first then like the nicknames for it (or not). I have some short names that I would use alone, and that I like a long version for too, but I can't decide if I like the short or long version more. Mostly, though, I think I tend towards the short version.

I haven't found a long version of
Vida or
Leo that I like yet.
