Recently I was at a family gathering and we were about to got out to have dinner. My 4 year old niece had just placed her shoes on and tied them up. Her mother said, 'your shoes are on backwards'.
I observed my niece looking in puzzlement at her shoes trying to figure out the mistake (I certainly recall my many moments at her age thinking how do I tell the difference about my shoes). I remarked to my niece that, 'perhaps her shoes are on correctly but it's her feet that are on backwards'. She was actually able to understand the question with a laugh.
As an adult, I find that people and events will still challenge me regarding what's on backwards. It is my shoes or my feet?
