I'm already planning to get a haircut tomorrow; I don't have a client meeting scheduled for Monday at the moment. If between tomorrow and Monday, a meeting is scheduled, then the haircut will not have been scheduled in order to look nice at the meeting.
But that's not what we're talking about.
If you already put in your public calendar that you will be getting your nails done in a couple of weeks; then a meeting is scheduled for tomorrow, and you arrive at the meeting with your nails newly (but very poorly) done ahead of schedule, we know that your plan did not go off as… well… planned. And we have one thing to point to as the probable reason as to why, and why your hair is still a mess, which is what you probably
really should address before a meeting. In addition, you can't (or won't, contrary to your stated communication policy) offer any other explanation why you arrive in such a disappointing state. This keeps happening when you have meetings scheduled.
Until a good alternative explanation for this pattern is presented, we can stick to our hypothesis that meetings really freak you out and mess up your beauty treatment schedule.
e: Gotta get those analogies in order…
