Turns out an older girl must have the exact same coat.
Cute story, though that older girl must have been freezing on her way home from school yesterday ;).
After searching through the tables of lost and found hats and mittens at school when my boys were young I swore off black mittens for good. Three long cafeteria tables of black hats, gloves and mittens. I never found the one we were missing. Heck-we homeschool now and we still lose gloves/mittens.
