How stupid people can be!
Have you ever noticed that some people just can't follow an e-mail conversation unless you reply with history. I could see this if a day or more passes inbetween e-mails but for some even if there is only a few minites gap, they can't rememebr what they were talking about. Ok so you have a short memory, LOOK IN YOUR SENT FOLDER!!!!!!!
If it's not right in front of them, they don't see it.
