We always exchange more than greetings, and when I told her I was engaged, her smile made the indoor lighting unnecessary.
Interestingly enough I had the same reaction from many at the Geneva Writers Group. Disbelief, more because of the fact that I was so happily single, then who-would-want-her reactions.
Some women have said I give them hope where I assume they mean they too might day find their soul mate. I may be generous, but I've no desired to share mine since it took us so many decades to come together.
If my happiness makes others happy, that's just another plus.
