Whenever I'm planning something and someone says to me, "The ball's in your court, Paul", I never know which sport we're playing.
Is it tennis? Ping pong? Completely different games. Different rackets. Different swings. Different scoring. Different rules. Plus, I prefer playing tennis using a ping pong net.
That's why the ball usually hangs out in my court, and I may not get back to you for a few years.
Sorry.
