To put it into even more realistic perspective, how often would she be called
Tabitha Isis Willis? Surely formally she'd be
Tabitha Willis, to friends and family she'd be
Tabitha, and when naughty she'd be
Tabitha Isis, right?
So would
Tabitha Isis Willis be used that much other in the first few weeks when your telling everyone her name?
I don't know, all together I think it's not too bad.
Isis Willis is bad, but
Tabitha Isis Willis... Not so much. :)
