"Padel" Ball

Mabel: [after having played once, a month ago] Okay, so it's easier with two pairs.
Javi: Yes, it's easier with four people...but, you have to hit the ball.
Mabel: Bwahah, oh, you have to hit the ball? Well I must've mistaken it the last time we played.
Javi: Yeah, I forgot to tell you that part of the rules.
