One of the great things about pickleball is that you get to play with other people. It is an inherently social game and that can make it extra fun.
That said, we recommend you think twice before having a conversation during the game -- certainly not during points. Between-point chatting slows down the play which can be frustrating for those waiting for your court.
And talking during the point (e.g. "on the line!", "nice shot!") can often be misheard as you calling the ball out.
Our recommendation is play hard, play fair and then talk about it all you like after the game is over. It makes the games run quicker and gets more people in on the action!
