I looked at my watch this morning as it lay on my nightstand and saw that it was 7:40 already. Since I catch a bus three blocks away at 7:51, I needed to hurry.
Ten minutes later, finally ready to go, I grabbed my watch and put it on.
When I looked at it the right way up, I saw that it was only 7:20. And I'm all ready to walk out the door. It must have been 7:10 when I only looked at the minute hand upside down.
This is also confirmation once again that I cannot estimate time. If I could, maybe I would know that I have an entire half hour extra.
