I've found a nice one that Snopes says is true, although a bit exaggerated. The real story
is almost as heartwarming - quite often there's a nugget of truth in even the most unlikely
one:

Personally I'm a big fan of good stories (who isn't!!) and I don't think there's a smidge wrong
with creating an inspiring tale to make people think or reflect. I enjoyed a really LOVELY
adaptation of Dickens' Christmas Carol (Scrooge et al) earlier this evening on the
television - a heartwarming tale, and utterly fictional - apparently to influence readers on
the miseries suffered by the poor in workhouses, ie. I understand it was written to spark
social reform as well as entertain (I could be wrong though). Anyway, it's a jolly good tale.
But I always run a google search on these stories before re-sending, and add the word
"snopes" to the search string - they're pretty good at weeding out the true from the 'as
true', and they usually provide the history of the tale.
I don't do this because I want to pour scorn on anyone but because the internet is awash
with good and bad and snopes is one of only a handful of sites that makes an effort to
help filter it - and in an even-handed way, rather than some bloggers who just poke fun.
Sometimes the stories are just as heart-tugging but have a less fluffy outcome - the Make
a Wish foundation is often inundated with people writing in asking them about the stories
that do the rounds about sick children who've supposedly made a wish. It just costs them
time and effort to have to respond to them:

I think there are plenty of genuine examples of kind-heartedness right here on the forum
