Well, after reading all this, I really think you are putting waaaay too much thought into this. I too am of the opinion that it would be nice if a card should be sent. Matter of fact, I probably would have done it without the request of the other trader. I also don't think the first message in which an extra card was requested was as much of a demand as it was a simple request. I'm pretty sure that the other trader is well aware that you don't have to send him anything and wouldn't have been bent out of shape if you didn't send something. No need to stress out over this and if you don't like what happened, just don't trade with him/her again. On a side note, I don't think anyone is wanting to convince you of anything, they are just giving their opinions, which is what you asked for... Just my $.02
