I agree that Mary Anne is probably the "cutest" and the kindest/nicest/sweetest of the group. :) I always really liked her for that; she's pretty adorable.
My *favorite*, though that wasn't the question, is Mallory--and we're "like the same person," too, lol (although I do also have a lot in common with Kristy, Dawn, Claudia, & Abby too...and a bit with Jessi and the rest.)
