If you could make one tiny act of kindness catch on everywhere, what would it be?

A natural way to answer

I'd love it if everyone made a habit of genuinely complimenting one stranger a day. It costs nothing, takes a second, and could completely turn someone's day around.

Key phrases to use

• pay it forward — to respond to a kindness by helping someone else rather than the original giver“She paid for my lunch and told me to pay it forward.”
• buzzing — full of lively, excited energy“The whole room was buzzing with excitement.”
