“The proper response, as Hanukkah teaches, is not to curse the darkness but to light a candle.”
Cursing the darkness still leaves you in the dark, unable to see and stumbling.
Better to do something about the situation. Even if something small.
Hold the door.
Help the old lady.
Be polite to the stressed-out clerk.
Instead of bemoaning the situation, becoming the solution is better.
Be the light that illuminates others and helps them see in the darkness.
