I wrote a bit previously about things to do to develop new friendships, and the last item on the list was "Hang out on your porch." Totally unintentionally, I ended up doing just that in the last week - not once, not twice, but three times.
All three times, I talked to a neighbor or two, and it was not "about" anything specific. We just had a really nice chat.
I could get used to that.
