Lizzy, I agree with Kalni. Maybe he was trying to "include" you in his trip? At least, to share with you what he was up to. Kind of reaching out in a way. I would take it that way, anyway. Trying to be more glass-half-full these days.
And he left you a message last night other than talking to the Ds, which shows he is thinking of YOU, not just them. So that sounds good, too....
