CarolC......I too have never been able to wear a watch, since about the age of eleven. But they don't go backwards, they all used to just stop after about a week of wearing them.Ended up with a drawerful of defunct watches.

Tried for a few years,if I received one as a pressie, and then gave up and carried a small alarm clock around if I was doing something where the time was 'important'. I thought I just had bad luck with watches? So there could be a real reason? Thankfully I now have a mobile phone which seems to be behaving, so tha alarm clock days are over.. Your masking tape idea sounds a good one.

However no trouble with sandwich orders. Had a lovely tuna and sweetcorn today, with all the ingredients in the right places.
