Oh, come on and open it! You never know what someone may be writing to you. Once i wrote a letter of amends to someone. they sent it back to me unopened. I was devastated, and also really troubled, as I had no other way to make amends. I found out months later that they were afraid to open it because they thought I was going to reem then out in the letter, while just the oposite was true. I've not opened mail or threw it away only to find out it had a check in it. you never know!
