Things you learn from the trash truck

Yesterday my sister and I took Evelyn to the grocery store. Evelyn pushed the cart around the frozen section, where there were convenient bumpers on each side of the aisle. She won't let anyone help steer; she knocks your hand away if you try. Eventually she started backing up, pulling the cart with her, and saying "beep beep beep." She knows to beep when she backs up. :)
