When?

Yesterday I was leaving for a day of business meetings. Here's how the conversations went:

6:50 a.m.

"When will you be back?"

"I'll be at Abbott Park all morning, then in Lake Forest with August Jackson in the afternoon. I should be home before 5."

6:55 a.m.

"Do you know when you'll be back?"

"Before 5."

6:57 a.m.

"You don't know when you'll be back do you?"

"Yes, before 5."

I got home at 4:30 and was met at the back door.

"There you are. I was just thinking, Bill should have been home by now."
