the conversation felt less relaxed than our last one, I think because he was expecting to be picked up at any moment, and I wasn't sure how much I should get into anything if he might need to interrupt me. I think this brought back an old dynamic I've been trying to overcome--where I would launch into a story regardless of whether or not he was up for listening to it, and kind of try to squeeze attention out of him because, in the past, I felt like I needed it or he owed me. Instead of just letting him go.
I didn't do any 180s... in terms of flirting or asking a ton of questions... but I think it's good that I finally called him, and that we had another comfortable contact.
