Say what?

It is raining here. Outside the bowling alley for a quick smoke, another bowler and I talked about the rain.
Me: Rain? Too much rain.
Him: You need the rain.
Me: I live in the desert.
Him: That's why you need the rain.
Say what? If it's a desert, it does not require a lot of water to survive, it has managed to survive all these years without it, why does it need rain now? LOL People here are strange!
