Everyone who knows me knows I am big and fat. If someone as asked to describe me, they would say "a big fat guy with a beard". And they would be right. I am big, I am fat, and I have a beard.
I have spoken about being fat before, here: http://thebanburyman.blogspot.co.uk/2011/01/f-word.html
Occasionally, people do pass unkind comment, and I deal with it as I set out here below.
Yesterday, at church, someone in a group of people asked me how I was, knowing I had been unwell lately. As we spoke, one person in the group piped up and said I needed surgery on my stomach, to make it flat.
I immediately asked why I needed such surgery, as I did not have a problem. There was a very long and awkward silence.
Now, when such things are said, I am well within my rights to take offence, and point that out. But I have found my approach above to be an effective one. Without causing argument, or losing my temper, I cause awkwardness and embarrassment, that make it difficult for the person to contnue.
As has happened every time I have employed this method, the person concerned later came and apologised to me. I explained that I had not been personally upset (which is true) but that what they had said was offensive (which is true) and that they did not know how I might take such a comment, and that comments like this can cause enormous upset.
