A relly, really bad hangover

You wake up, your vision blurred, your head feeling like a team of construction workers is cutting it with rotatory saws.

"Oh, my head is killing me." you think. "Where am I? What happened?"

You try to focus on the party: the last thing you remeber is Margaux pulling you away from Mark. You have absolutely no idea about what happened afterwards, or how you ended up wherever you are.

"Oh, I will never drink that much again."

After a minute, you realize you are staring at your room's ceiling.

"How did I get here? Where is Margaux?"

Suddenly, you feel something moving in the sheets to your right.

"Oh my God, did I sleep with someone? Margaux is going to be furious... Well, unless it's her."

You look to your right, anxious to know who the mysterious person is.
