Whoever taught you chess, spades or how to dribble gave you a lifetime pass to a whole world. Teach someone else.

Being taught a game is being handed a permanent membership. Somebody spent an afternoon explaining the rules, probably badly, and as a result you have access to a whole world of people, evenings and arguments for the rest of your life. That transfer costs almost nothing to make and never stops paying. Most people never think to trace it back.

Name the person who taught you yours, and tell them if you can. Then do the same for somebody, which mainly means being patient while they are bad at it. An afternoon of your time is a strange bargain when what it buys them lasts decades.
