I live on the east coast of the US where there has been a major weather front that has produced a huge amount of rain this weekend. We are soaked! 
Yeah we had rain here yesterday, but it wasn't too bad. Left the cat out though and he was drenched when he came in, poor kitty
Well, it's not all bad as rain helps with crop irrigation and provides water for hydroelectric power plants. 
But what about floods! They destroy houses and kill people!
Well, that's true! There was some flooding in India in 2015 that killed 500 people and displaced 1.8 million. I can't imagine! 
Yeah, let's ban rain! It's up to no good and I don't think there are many more benefits than what you mentioned!
Who could forget Hurricane Katrina? One of the costliest natural disasters in US history. Rain is definitely up to no good! 
Yeah, I wonder what happens to it when it's been on the ground for a while. Does nature get revenge on it?
