So here's a scenario for you. And to be clear, I am not asking for advice, but interested in how people handle this. A bandleader calls you for a gig a month away. You look at your calendar and see that you will be coming home from a family vacation two days before. You really don't want to do the gig. So you simply say, sorry I'm busy and I can't do it. Then the bandleader asks you what you have going on that night. Are you honest and simply say, I just don't feel like playing that night, or do you make up a story?
