Secret Message
To the person who made a point of asking to be on the committee: When I ask about availability during business hours, and you tell me that there are 24 hours that you can't meet and only 16 when you can, I'm not going to take your constraints as seriously as everyone else's. Based on the information I have so far, there is no time when everyone can meet. I'm going to have to pick a time when one person can't be there (of which there are six possibilities). I'm most likely to pick one where you can't be there but I know you're not teaching. Especially since it's likely that the last time you did any research was for your master's thesis, many years ago, so it's not like you need to set aside "writing time." (And I know that you don't have any advisees, either.)
