We're coming [from Pennsylvania]
Dear Sean. First, if you hit the ball and it touches any part of your inside line, albeit a centimeter of it, are you out? Second, is there any spiking rule in the men’s league that you play or are you allowed to spike it as hard as you want? Is this frowned upon in competition? Third, is blood on the serve only when the serve is unreturnable or also when the receiver plays a shot off the serve that is unreturnable. Fourth, how is a showdown actually performed?
