Wait a minute Mr. Postman?

Can't blame the Postwoman for this one.

After guests checked out the other day, I went upstairs to start cleaning and found several pieces of my mail sitting on the table.  Weird, I thought. Why would guests pick up my mail?

Several hours later a friend contacted me. She hadn't yet gotten my RSVP to her wedding invitation.  What invitation?  I never got it.

After some checking, I realized that I also never received that month's water and cable bills.

That's too much of a coincidence for me.  The only conclusion is that guests have been picking up and throwing out my mail.  Now, why the hell would they do this?  Don't know but apparently it's another thing you shouldn't have to tell adults that I will now have to warn them about.
