"I love mankind; it's people I can't stand." - Linus VanPelt
Thinking requires less work than doing. "Loving mankind" reflects intentions or altruistic feelings. Feelings are fickle, fleeting, and frankly aren't worth a hill of beans.
True love involves work. You DO things for the people you love. And sometimes for the ugly people, the mean people, the ones who do nothing and never will do anything for you. That's love.
It's easier to care about the Rainforest than to clean your room. Caring doesn't involve work.
It's easier to wear a pink ribbon, and feel self-righteous about it, than to empty the puke pail of a breast cancer patient on chemo.
But nobody sees the puke pail. People SEE the ribbon. It shows how much you CARE. It does not, however, show how much you DO. If you need an audience, then reexamine your motives.
"The proof of love is in the works. Where love exists, it works great things. But when it ceases to act, it ceases to exist." -- Pope St. Gregory the Great
What are you going to DO today, to show your love?
