I must have been abducted by aliens yesterday morning. It is the only explanation that makes sense. This morning I went to make coffee and the pot still had my second cup of coffee in it, and the coffee pot was not cleaned up as I always do. So I did not drink my second cup of coffee, and the pot turned itself off as designed.
The only other possible explanation, is I go so busy at "work" that I forgot my second cup of coffee! That is less likely than abduction by extraterrestrials, so eliminate the possibilities and whatever is left has to be the truth!
