Ever since my high school class celebrated the fortieth reunion of our graduation last summer I've gotten quite a few Facebook friend invitations from fellow classmates. Some of them I knew well back in the day, some I knew slightly, and some I barely knew at all. (I my defense my class was huge. There were approximately 800 graduates that year.)
Some of the ties had a commonality, but others had me scratching my head. I finally gave up and sent a message to the person asking how they knew So-and-so. After some back and forth we figured out that the mutual link was a program for teenagers some of our children were active in fifteen years ago. The other common friends were business associates of hers that I knew from a retreat program Hubby Tony and I have participated in the past few years.
I guess it just goes to show it's a pretty small world.
