a hobby to share with them...
Actually this post made me stop to think. I'm not sure how I would feel receiving money from being neighborly.
But I am a country bumkin :cowgirl: and would use the money towards a vegetable garden to share with them! Grow your own veggies, and delivery a basket once a week of whatever is ripe. Or encourage them to visit the garden and help out/pick their own.
Not sure about the age of these neighbors, but working in his garden is what my retired dad loves to do!
And if you don't want to put in fall veggies, plan your spring garden over the winter.
Sounds like you are lucky to have such kind neighbors!
