It’s already (2 minutes) past 10 now, I’ll start being productive at 11.
But now I feel peckish and 11 is almost noon, I’ll start after I had lunch, so I can concentrate better.
Well, at 1pm I’ll have to start preparing to leave the house, and that’s just half an hour from now.

“So, did you change the bed sheets like I asked?”

THERE WAS NO TIME!
