Do you know that sinking feeling you get when you realise that you just spoiled someone's hard work and planning with a loose mouth, even though it's all just a misunderstand and you really didn't mean to do it?
Something like in those movies when a bunch of people are hiding from a monster, and you're the one who decides to risk a sneeze or laugh just before the monster is out of earshot?
Or maybe you're among a bunch of rebels waiting to ambush the enemy in the streets, and you see the enemy escorting your mother as a prisoner? Then, being the total IDIOT that you are, you just can't resist the temptation to gasp "Mum!" and end up giving all your allies' position away?
Well, i'm the one who sneezed. I'm the idiot.
And i'm experiencing that sinking feeling right now. In buckets.
