Can embarrassing punishments given by parents be considered abuse?
To punish my younger half-brother, my mother used to strip him naked and have him stand on one leg in front of her, and sometimes in front of both of us. She used to say that 'nudity is the most effective punishment for boys'. My mother was a wonderful woman and I don't think she ever did that for abusing.
