Well, thank you all for your suggestions on names for the new girl (pet shop find).
Much to my surprise, Karl - who is supportive of my passion for the ball pythons, but really doesn't wish to interact with them - asked me if he could name her. I figure anything to get the big guy more "invested" personally is a good thing, and I was touched that he wanted to name her. So, he asked for the weekend to think of a name for her. I waiting anxiously, because I really hoped he didn't pick a "silly" name.
He just told me that he'd like her to be named Sarah. Amazingly, it seems to fit her gentle disposition! I just looked up the meaning, and it's Hebrew for Princess. Perfect for my new princess!
Anyway, I think Karl did a great job naming her and she is no longer Ms. No Name!
