I’m nervous about the party.
It’ll be fine.

But what if the weather’s awful? What if no one comes?

What if everyone comes and there’s not enough room and a fight breaks out in the kitchen? We only just redecorated the kitchen!

Hey! Calm down! Listen, honestly, it’s all going to be fine.

It’s just a few friends coming round for a fun evening. Really, what’s the worst that could happen?

Well…

Rrrrraaaaaa!

That… doesn’t sound likely.
Those who fail to prepare for surprise ghost-dinosaur attacks, prepare to fail.
