Has anyone ever answered one of your questions in such an ignorant or nasty manner that it genuinely upset you?

It's sad but it is a fact of life that on all networking sites like this it does happen. People who are as timid as mice in real life can get a kick out of being (or pretending to be ) hard on here. If you met them in the street they would not have anything to say. Do not let them upset you, the majority of us are reasonable friendly people. Ignore the idiots and enjoy the site
