Kind of like it, kind of don't. It's fine until you get to the final B. That's where I lose some love for it. I love the nickname
Cal, but I don't find it springs naturally from
Caleb, because the first syllable of
Caleb does not sound identical to
Cal. I used to think that I'd name a son
Calvin, which I love, to call him
Cal, rather than
Caleb. That was until people here pointed out that
Calvin is reminiscent of
John Calvin, the leader of the Protestant Reformation. So I'd have to rethink that. For my fantasy life in which I'm still young enough to have children and want more than two, lol.
Sorry, I digressed quite a bit but I'm not erasing it!
