Thanks for these further responses. Its coo l now, I was just being silly. I thought it was quite a serious gripewhen it happened, but time is a healer, also I could have been a bit more tactful myself. It doesn't matter who the argument was with now and its best left in the past but basically I was correcting a bit of mis info in a way that in normal speech where I live would be funny and matey, but on reflection comes over quite differently when written down (and that other person is from another location) so I can take some responsibility and leave it there.
