Or at least your local community?
I have seen cute little free libraries and honesty boxes where people sell eggs and fruit and veg, someone has put out their spare plant pots in their garden for passers by to take.
There is a group of litter pickers, a speaker group of tree planters, someone got a few benches and planters put up on a spare piece of grass and it's all lovely things that make the local community a better place.
reading the school supply page, wouldn't a good idea for the summer holidays be to gift the teachers school supplies instead of flowers and chocolates and wine?
oh I have also seen people bringing their old books to town centers, leaving them on benches with a note saying 'please take'. I just think it's lovely.
Or even the lovely women on busses or in shop lines who see a struggling mother with a child and instead of berating them, they either share a few kind words or reach into their bag with a small wrapped sweet for the child to calm th down.
Once on a bus my children were crying for a drink and someone went rooting in their shopping bags and gave my children drinks from a multipack! Those people really did improve the world!
So have you? or How would you improve the world?
