Well, I adore
Christopher. It's probably my favorite boy's name. Can't say the same for
Topher, though.
My creative nn for it is
Risto, but I don't like that as much as full
Christopher, which is why I'd probably never use it in the first name slot.
Topher's okay for a child and adult though, and I suppose wouldn't mind seeing it on either. It
is cute for a hamster, though. :D
