Idiom: It never rains

As we experienced severe rain last weekend, I was reminded of the expression: “It never rains”, or the full version “It never rains but it pours”.

It is used to express that only very bad things seem to happen (“pour” means very heavy rain) and not mild things (rain).
It’s kind of pessimistic, but it is used when several problems occur at the same time.

For example:
A: “My car needs some major repairs, and my boss told me we won’t be getting any bonus this year. Also, my refirgerator has broke!
B: “Oh dear. It never rains, right?”
