I've now heard from two people who never got the invites I mailed out last Tuesday. One of them is my mom and the other one is one of the groomsmen. I mailed everything together, and put all the invites in our out box at work that goes straight to the post office. I don't know how they could have gotten lost or who else might not have gotten theirs. ARGH, guess I'll have to call the post office tomorrow to see what's going on.
