Twice he got up and left the table--once to get a drink and another time to use the bathroom--and both times he ended up standing next to his bandmates at the bar and talking to them for a while, while I was sitting by myself. I couldn't tell if he was trying to escape me, or if he was getting roped into conversations with them, or what was going on.
In the past I would have been really mad, but this time I just felt genuinely awkward. I wondered if I should have brought someone with me so he didn't feel obligated to 'babysit' me, but then I wouldn't have gotten to talk to him about anything.
At one point while he was at the bar he made eye contact with me while talking to the mandolin player in his band so I stood up and walked over and introduced myself and talked to him enthusiastically for a while about the music. After several minutes of animated conversation there was an awkward pause for a while and B asked me if I wanted us to sit back down at my table.
Earlier in the day I had visited a friend who works for a music publisher and they were getting rid of some awesome stuff... so I picked up two little music scores that I thought B might be able to use and I gave them to him at his gig. He scrutinized them and said thank you. At some point I told him I felt like I was keeping him from hanging out with his bandmates and he said that he didn't want to be rude (I couldn't tell if he meant he didn't want to be rude to them or to me) and that I wasn't in town all the time so he wanted to be sure to get some face time with me. He said, "thanks for being sensitive".
Overall he talked to me one-on-one for maybe an hour after the gig was over.
He asked me what my plans were in new york for the rest of the week and when I told him I was leaving the next day he looked really surprised.
B also didn't introduce me to anyone who approached him to talk. I don't know if he was actually just being rude or if he was just tired and didn't know how to introduce me.
