I know what you mean about coming across as sarcastic or nasty, I posted a comment on a thread when I hadn't been here very long just to be told that was ridiculous. I was contemplating not posting again but then I thought, sod it, who cares, we are not likely to meet the other people so here i am, still here.
People seem to be much more sensitive and touchy these days, don't know why.
My partner frequents a site where they tell you to don your asbestos underwear before you come in!!
