There was a time when altruism was considered the obvious way to live.
Then along came the Thatcher 80s - and suddenly altruism was equated with stupidity.
Greed and ambition were to be celebrated and admired.
And we've never recovered.
But every so often something - or someone - comes along who reminds you that human beings still have the capacity for acting in a way that helps others, while bringing them no material gain - apart from the satisfaction of knowing you have been kind and made a fellow human being feel good.
So yesterday, my boys went to the park with 3 friends.
They were only going for an hour in the late afternoon, so I didn't bother giving them any money.
One of the friends bought 2 ice creams and apologised to the others for not having enough £££ to buy them each one.
'You 3 not having an ice cream?' the man asked.
'No - it's ok, thanks,' the boys replied.
'We don't have the money - but that's fine. Thank you.'
You can guess, can't you?
Not only did he give them each an ice cream - he even gave them strawberry sauce!
Now that man's never going to be rich.
But he made their day.
And when they told me, it made mine too.
And now I've shared it with you.
We don't know his name, so he has no way of knowing how far his actions are being celebrated and lauded.
He won't even have the satisfaction of knowing how much they have been appreciated.
But he put a little bit of goodness into the world.
Can you put a value on that?
PS Still having some techy problems.
