I said other. I wouldn't say that unplanned cancellations just don't affect me, but it's not like I have a tantrum when they happen. As for planned absences for T vacations or conferences, I prefer to know as far ahead as possible. I also appreciate knowing ahead of time how much time my T is planning to take off for various holidays. I will never ask, as I don't like to communicate neediness, but I find it reassuring to know ahead of time.
