*sighs* This is why I prefer to meet people when we both going to convention. I'm frigging so shy, it's painfully hard for me to talk to people unless I'm really really comfortable. Then I went to my first HP convention - granted I didn't say much, but it was so nice to be around fannish people who like the same shit as me, and even if I didn't say much the first time around, they knew I was enjoying myself. The next HP convention was much easier. Hell, the last HP convention, I actually did a fan fiction panel with some fellow fannish friends and didn't have a total melt down.

But yeah... even if the friend was shy, "please, and thank you" is always a must!!
