Much as I hate to be a pedant...

firstly, you did not "sell" the CDs, Lizzie. Secondly, the thread you have linked to says there were two CDs available - you bought one and someone else bought the other. This does not equate to you selling "quite a few of Ralph's CDs."

"I realise that you, Ralph and Diane are all very, very close buddies,"

I understand that it serves your purpose to believe this, Lizzie, because you can then give credence to the idea that there is a cohesive group of people who are out to get you. Diane and I have never met. Ralphie and I have met a few times in real life, because we've been at the same events. That's it. All three of us have disagreed with you quite strongly in the past, but that means no more than the fact that we, as individuals, disagree with you.
