Dear Ann Landers:  My 5 year-old has been asking me 4-5 times a day if I brushed my teeth.  I was really getting paranoid and started walking around popping expensive breath mints every five minutes.  Finally, I asked him why he was saying that to me all of time and he said, “Oh, mom.  I just like messing with you.”  I sort of wanted to kill him, but I remembered he was not an accident.  Geez.
