person A: Recently_comma_ I've been watching my son play a game called Fortnite. It blows my mind how good he is at such a fast game.
person B: I have heard about that game.  I heard there was one guy that makes about $500_comma_000 a month playing it on the streaming service Twitch.  Maybe your son should give it a try.
person A: I have never heard of Twitch.  That is a lot of money_comma_ I could retire!
person B: Twitch is just a place where people stream themselves playing video games.  I guess a lot of people really love watching good players.  Go ahead and retire now and get him started!
