Today a friend of mine was trying to mail a fat envelope, hoping that they could get by with just a regular stamp. I can imagine the snide comments big letters get when they get to the post office:
Letter 1: "Can you believe that letter thinking she can squeeze into a 39 cent stamp?"
Letter 2: "I noticed she had been putting on a little weight, but I was afraid to tell her."
Envelopes can be so unforgiving.
