THE LITTLE GREEN MAN
There once was a little green man living in a little green house on the top of a little green hill. One day the little green man wanted to take a bath so he went and took his little green bottle of shampoo and his little green bar of soap and also his little green towel and into his little green bathroom he went.As he took off his little green shirt and his little green pair of shorts, he stepped under his little green tap and started to bathe. Just then a saleswoman came to the front of the little green man's house and rang on his little green bell. "Ting Dong".
The little green man heard his little green bell and he thought that his pizza had arrived so he hastily took his little green towel, wrapped it around his little green waist and rushed to the door. As he opened his little green door, his little green towel came undone, and dropped unto his little green doormat, exposing his little green, uh...thing.The saleswoman gave a shriek and rushed out of the little green house. In all her haste and all her horror, she did not see the truck coming at 120 mph which struck her, killing her on the spot.

Question: what is the moral of the story?
