It’s nature’s way

There is some physical law out there, up there with 1+1=2 and gravity.
If it is important for me to get a good night’s sleep, something will prevent that. So, if for instance, I am up until 2:00 in the morning for a flight the next day, it’s pretty important that I catch up on sleep. In such a case I should not be surprised if the phone rings at 6:00 in the morning with a wrong number.
