Larry, that is very interesting and sounds wonderful. There are so many men who seem to wander about like lost souls after they retire. You sound like you have a very full and rewarding life. Our church in Aberdeen also had a men's breakfast group and there was a very active group of retired men there who were involved in lots of things, with and without wives.
My parents-in-law do absolutely everything together - I always envy them their close relationship, but I do wonder how my FIL in particular would cope on his own - however, the children have already agreed that in that event he would come and live with my husband and me, as he is such an avid reader and book collector and has more in common with me than any of them.
Callie - my mother was widowed at the age of 39, so has always done things on her own or with friends, groups, etc. I would say she has a very full life, although unfortunately I don't think I have inherited her socially-confident gene.
Babi - your mention of Brownies struck a chord, as I absolutely loathed it - my elder daughter, who is not like me at all, loved it, but my little one, Madeleine, is like me and found it so stressful she begged to give it up. Similarly, elder one is into every orchestra, ensemble, etc that she can manage, whereas younger one would rather eat glass than participate.
By the way - what is a Red-Hat? We have things like the Rotary, but I've never heard of Red Hats.
