Crazy Friend: I think I drank [Friend Whose Name Starts With 'I']'s blood.
Other Friend: ... What?
Crazy Friend: I think I need to drink some water.
*He goes off to drink water from the nearby tap, and soon returns.*
Me: So ...
Crazy Friend: Hm?
*I turned to look around, and end up seeing the 'Friend Whose Name Starts With 'I' walking down the stairs, so I call out to him.*
Me: Hey! Did [Crazy Friend] drink your blood!?
*I turn back to my Crazy Friend.*
Me: Dude, that's creepy.
Crazy Friend: *Shrugs* It isn't that bad. I mean, drinking his blood might be good for me. FWNSWI is a player.
It was at this moment when I decided to leave.
