I realized something today-- people's recollections of conversations are often muddy. People's interpretations of decisions are often different . Did he know for sure you had made other arrangements? Maybe he was trying (in his way) to make sure there was a solution? Maybe you don't like his tone. But one of the beautiful things about your sitch is that you don't have to care about that.
DETACH. Take a breath, mutter a choice word under your breath if you feel the need to, give thanks that you were able to make alternative plans and LET GO.
