You don’t need a reason
If you look at the world, it’s very easy to get dejected. The situation you find yourself in, often you hope no one finds themselves in. But this is all the more reason to be kind and caring. If you spot someone in a spot of bother, and you have the ability to do something about it, do it. Pay it forward. Not just for your own sake, but as a matter of common decency from someone who knows how tough it can be.
There’s nothing stopping you from being kind.
