you don't know what the weather will be like!
what we do know is that Prince Vegeta won't be able to close the roof if its not raining this year!
Yeah, the roof has been Rafa's problem in Wimbledon for almoat a decade now. And why are people even building roofs? We all know tennis is best played when the sun is in your eyes, the wind carries the ball, and the surface is worn down because of the weather!
