Left is Right and Right is Left

My daughter goes to Occupational Therapy once a week. For the last few weeks V's therapist has had a master's degree student working/shadowing with her (so she can finish her degree I assume). Today this very nice lady put my daughter's shoes on the wrong feet (they take off her shoes so she can use the toys on the play mat). I did not even notice until we got to the grocery store. Made me chuckle. The young lady has much to learn.
