Click It; Don't Lick It!
Who doesn't like it??!! I like it Almost as well as a physical letter. Except you get jipped from R-I-I-PPING open the envelope! Same goes with licking the seal, and a stamp when sending!
But the up-side is: disposing of the "trash" is a Click! ' Saving a tree today, is a click away!' Ha! I should be in advertisement!
