A couple of years ago I was on holiday in the Dominican. One night,in the restaurant, the man on the table next to ours started asking me about my hair! Wig. He asked me how I had got it curly and if it was permed. I replied that it wasn't naturally curly and smiled hoping that would be that. But his wife kicked him under the table and apologised to me for her inquisitive husband. He told her 'shut up -you don't know it could be a WIG', enough was enough so I said 'well yes actually it is a wig'. He carried on asking questions, it dawned on me that it didn't occur to him that I was wearing it for a reason other than I fancied a new 'do' for the night. So, I then found myself explaining (god knows why) that I didn't have any choice and I had to wear one for medical reasons. In fact he was a hairdresser.
In my younger days I was extremely slim and strangers used to think it was acceptable behaviour to tell me how thin I was! I used to eat like a horse and would have to HATE explaining that it wasn't through choice. I doubt the same people would go up to obese people and point out how fat they are!
What makes people think it is acceptable to make comments to strangers about their appearance?
