As I've mentioned before I belong to a Thespian group..... fellow actors I attended college with in the late 60's. I had not seen them in nearly 50 years and found them on a Facebook group.
I belong to several other groups as well.... mostly friends from the past but a few in which I do not know the people but we share similar interests. Astronomy. Hunting. etc. I really enjoy those groups.... even if I visit infrequently. - JamesJM
