Tennis looks so fun, but I don't know anything about it
Tennis IS so fun!  It is probably the most popular racket sport in the world.  I have only ever played singles tennis, but people who play doubles love it too!  Are you thinking of taking lessons?
Oh no that's way too much commitment, I'm debating on whether or not I should watch it on TV. So how do doubles work? Is there more than one person per team?
Yeah Doubles is two players against two players.  The court becomes a little bit bigger and you are allowed to hit the ball into the second wider set of lines and it is still considered in bounds.  Looks pretty hard,
