From Steve Rose's View from the Cop:
"Sandy Springs PD officers received a call to a home on Sept 1 around
15 minutes after midnight. The resident saw a man in the back yard,
looking into a window of the home. The officers got a lookout and a
few minutes later found a man who matched the description.
The officers asked the guy what he was doing and he replied he was
going around looking to solicit customers for his grass-cutting
business. Asked why he chose the midnight hour to advertise door to
door, he said he forgot to set his watch.
This is a common problem. I often forget to set my watch and suddenly
realize it’s midnight when I thought it was only 5:30."
