“My friends, love is better than anger. Hope is better than fear. Optimism is better than despair. So let us be loving, hopeful and optimistic. And we’ll change the world.”—Jack Layton (1950 - 2011), His final letter
Never expect someone to feel grateful. Ever. Just don’t do it. It’s always better to be pleasantly surprised when someone expresses genuine gratitude, as opposed to being constantly disappointed by a world full of petty thoughtlessness.
While you’re at it, try not to be all pleased with yourself for doing a good deed. It’s just a manifestation of your ego, and that never layers well with expectations of gratitude. It’s also the kind of thing that turns selfless acts into selfish ones, and the resulting emotions are the inevitable building blocks of resentment.
