Everybody's favorite Aunt!
I have been marathoning through most of the series with a new "convert" and a great idea for an icon came to me: Aunt Lula. I have no idea how many times Emmett says, "Just like my Aunt Lula used to say..." But Aunt Lula was always there to make him feel better, and solve all kinds of problems.
Maybe it could have a picture of boysenberries (for when she dyed Em's pants purple which [he] accessorized with a yellow sweater and pink scarf) or any of the other wonderful things she said/did for sweet Em.
