My girlfriend says she wants to go to bed early today but I think she won't manage.

She is planning to have dinner with a friend after work (she gets out of work around 6:30), finish dinner around nine, go to the gym by taxi, train for forty minutes, take a shower, and go to bed by 11 pm. Do you think she can manage?

I'll resolve this market tomorrow.

Yes if she went to sleep by 11.

No if she went to sleep after 11.

N/A if she went to sleep by 11 but she didn't have dinner with her friend/go to the gym or take a shower.

I won't interfere with her goal, I won't meet her today, but she will send me a message when she is in her bed.
