Care sharing

Yesterday, while waiting for the train, I saw a homeless feeding some birds outside.
And I questioned myself right away - How many times I've done that? And the answer was pitifull.
 Never.
I have never deliberately shared some of my food with any kind of homeless/free animals. And what's even worse - I never saw other doing that either.
I think we should stop sometimes just to give our time to others, people, animals, anyone who would cherish our attention.
We should give ourselves to others.
