1)I come from Grey clouds

I make the leaves fall from trees

I only fall on really, really cold days

I can change things from wet to dry

2) I think it isn't right to fly a kite at night, because you are not seeing where the kite is flying. It can fly to the road accidentally, and fall on the driver's view mirror, so it will cause some crashes on the road, which can also cause a fatal end. So, it is not safe to fly a kite at night.
