nothing to do with horses but my older daughter kept forgetting to put her shoes on when going to school. She would get into the car barefooted then as we got to the school "oh daddy I forgot my shoes… OK once, then twice but third time I just told her she could remain barefooted at school that day
Just happened that day they had a visiting missionary come to talk about how kids in very poor areas have no shoes. Every one looked at my daughter at that point … well she never ever has forgotten her shoes since
