I hope so - A weak attempt to sound positive when you know everything is

A weak attempt to sound positive when you know everything is about to blow up. It’s like a bad joke told by a sad person.

I hope so. My car just broke down and it’s raining.

I hope so. My dog just stole my lunch and ran away.

I hope so. I just got a text from my crush and he said ‘I’m with someone else’.
