We were in the launderette today and my OH made a lame joke about a sock dropped on the floor saying that 'that's my sock'. The lady who had dropped the sock turned on him and said it wasn't but in a very nasty way. I explained that he was joking and she Shouted at him in a very vicious voice saying she had come to do her washing quietly and didn't want his jokes! And did he want her blouse as well. It was so vicious and unexpected. I asked her to calm down and she got worse. I know his idea of a joke is not good but he didn't deserve that verbal attack. How I kept my cool I don't know but I do know that if my OH hadn't been there looking shell shocked I would have had a real go at her. The whole episode upset me greatly. He of course forgot it quite quickly. Sometimes because their illness is invisible people have no patience . Had it been a child or someone with obvious learning disability I'm sure it wouldn't have happened.
