“This is not my responsibility” is true more often than we think.
You can still care though. Most often you should.
Caring doesn’t give you the responsibility though.
Caring gives you an opportunity to see what change might be necessary, what help might be welcome. Caring gives you an opportunity to share your ideas. Caring gives you to possibility to change the world.
It’s still up to the one responsible to decide. Even if you are persuaded to be right. It doesn’t mean that you should stop caring.
