Absolutely right! Most of my substitute teachers were completely unqualified for teaching--they just happened to be friends or relatives of the absent teacher. In 5th grade, our teacher's sister, a woman that had to be pushing 80, would periodically hobble in with a cane and a knitting bag and tell us to do whatever her sister had assigned us to do. What I remember most about her is that she wore these non-elastic stockings that, as the day progressed, would sag and sag until they were bunched around her ankles ((((shudder))))!
