I had the same problem with 2 managers at this one place I worked. They were about the same height, size, weight (which was not inconsiderable, but I digress) and similar hair-colour & their names were similar ("Marcy" and "Mary".) For the first several months, I kept getting them mixed up, which annoyed the hell out of both of them, especially since (I found out way later) they actually didn't like each other... So I know how Ember feels... (Took me a long walk to get to the well, but I got there eventually...)
