As it turns out he didn't contact me at all to firm up arrangements, even though it was his suggestion to meet. I am not surprised by this (as I also said no to him regarding an issue for the very first time this week) but now I'm wondering whether to call him on this or whether to leave it, as it is so discourteous (to put it politely!). My quandary is when is it a boundary and when is it a telling off?
