One of the things I don't like about buying and selling on ebay is the fact that you deal with people who, in the written form at least, come across as total morons. I think it shows a lack of intellect or respect (or possibly both) if you can't use language effectively when dealing with people. I don't expect the works of Shakespeare, but I do expect things to make sense.

In addition, I expect people to be constructive and positive when using ebay, rather than make up their own way of throwing their weight around.

I'm not an English teacher.

I offered him a refund. He's not accepted it.
