I think of myself as somewhat outgoing. However, those two days, at those two meals, I felt completely invisible. The first day I was not even spoken to at all. The second day, I was barely included in a couple of comments because I inadvertently sat in between several folks from the same company.
I generally don't mind being by myself and enjoy traveling to these conferences as a change of pace from the normal routine of work. But, for that hour those two days, I wanted to run screaming from the room. Which, of course, I didn't do. I did eat as quickly as possible and then left to find other things to do for the remainder of the time until the next session started.
Last night I was invited to a middle school choir program. The kids picked songs from the 1960s and choreographed a routine with the song. It was cute, but made me feel old! I dimly remember middle school....and wouldn't wish going back to that era on anyone.
