"Hey buddy, can you spare a dime?"
We can all help make the world a better place to live in without even involving our purse/wallet, and requiring only a tiny amount of time. These 'dime time' acts of kindness to our fellow human beings can help reduce stress in others and therefore contribute to a happier world. Here is an example of what I mean - bear in mind that in the UK we drive on the left.
You're driving in your car towards a set of traffic lights on a crossroads. It's your right of way straight ahead, but you notice another vehicle on the opposite side of the road indicating to turn across your path to the road on your left. There is a queue of other vehicles stuck behind this vehicle. Do you drive on thinking to yourself, "Well that's their problem!", or do you say to yourself, "I know how I would feel being stuck behind this person, and who knows when the lights are going to turn red, so I'll give way to him/her so the others can get moving"?
I'd like to hear of other examples of opportunities for 'dime time' altruism.
