My home group meets on Friday evenings. One member was sick. One had to work. One is getting ready to travel this weekend. One had another commitment. DId not hear from the others. So, tonight the meeting was just me.
There have been times when I was the only person there and newcomers showed up. So, I stayed for a while in case a newcomer arrived, or in case one of the other members was just running late. I got caught up on my daily readings. I did a bit of study. Then, I left.
