Yeah, I realize the popularity. It's probably the one name everybody in the world recognizes at popular. (I looked it up.)
I've heard of
Nat but Tally is new. At the character's school there are two Natalies besides her. One goes by
Nat and the other was to go by
Natalie Marie, her full name. But now, the second one can go by Tally....or maybe Tallie as a reference to her height as well.
Thank you! =)
