One of my good friends always goes to meetings on Thursday nights after work. At first I never questioned what the meetings were about, and he never really expounded on that. It was fine that he went to meetings every week and I knew better then to include him in any plans that might fall on a Thursday because he would not be available.
But like every absolute, we humans like to challenge them on occasion. I imagine that is a big problem for the wives of celebrities, wanting to so something with their spouse or family and being restricted by a schedule. It is always tempting to try to get an exception for one “good reason” or another. But a professional cannot afford the luxury of canceling a commitment or they risk getting a bad reputation for not showing up – and that can be a career killer.
