Ms. Bug is right! Leave it! You can't tell her to look, you can't ask if she looked, you can't ever do anything to try to figure out if she has read it. Remember, you really sent it for you, knowing that she might not even open it. So, looking at it that way, you've already succeeded!
Agreed.. i will never ask.. and i won't even snoop anymore.. i know her passwords, but will NOT do it..
