None at all

You feel yourself getting very sick. Your stomach hurts, and you don't really see yourself getting inside a car for a long drive anytime soon.

"What's wrong, man? What did you eat?", your friend Gary asks you, but you're not quite able to answer that. You excuse yourself and run to the restroom.

Some time passes, before you hear a knock on the door.

"Everything alright with you?" It's Gary again.

"Not really," you say, "I think I ate something bad... and it doesn't seem like I'm over it!"

"Oh fuck, man! You know we can't wait for you! We got our finca booked and everything!"

"Yeah I know, you don't have to. Maybe I can follow you after I get better. But for now, there's no way I'm leaving this toilet!"

Your friends aren't happy with it, but given the circumstances, it's best for you to stay home and get better. What an evil twist of fate to spend summertime at home where the bath is near!
