Sir ... it's time for your pre-meeting, sir ...
If you don't mind, I'm in the middle of a meeting now ...
You asked me to tell you yesterday ...
So, why are you telling me today?
You told me to tell you tomorrow yesterday, and that would mean today, sir ...
Couldn't it wait till later ?
You specifically told me to tell you now yesterday, sir ...
Uh, right. Seems we have a problem here. It'll just have to wait until this meeting is over ...
Shall I reschedule the pre-meeting, sir ?
By all means, you should reschedule the pre-meeting now ...
Now would conflict with your schedule, sir, as you're currently in a meeting. Perhaps later, sir ?
Good point ... make it later then ...
You have some time available right after this meeting, sir ...
Sounds like a plan. By the way, what's the topic ?
You requested it to set the agenda for THIS meeting, sir ...
Hmmmm... well, looks like we'll have a better idea of where we want to go with this shortly ... I'll get back to you.
