We're a fan of distributing Random Acts of Kindness here.
Over Christmas especially, I learned from Lorax to really extend that idea, and we recently gave away fans ordered in advance on eBay to people waiting for buses and taxis, stamps to elderly people at the post office, and other little goodies. Lorax is the Queen of the Christmas Random Act of Kindness though.
So we're trying to continue this idea. My first thought is always food related, but even I would be a bit wary of a stranger giving out food or lollies :-O
Can we come up with a list of ideas to make other peoples days brighter?
