What would te do if te discovered L sitting on your bed?

I would probably scream at first from not expecting them but then I would get some strawberries and sweets for him and try to talk about stuff. he'd probably get bored with me though.

Well, how about I put it this way:

NOTE: L and Light are handcuffed here, I am sleeping

L: *staring at me, inches from my face* Is she going to wake up?
Light: *grabs the bridge of his nose* Not if te do that.
Me: *slowly opening eyes*........ huh....... Ah *falls head first on the floor* What the f**k are te doing, are te trying to rape me!?
Light: *ligtly smacks L on the back of his head* That's not how te wake up someone.
L: She is up, and that's what is importaint here
Light: That's not the point.

Soon Mortal Kombat in 3D and handcuffs starts

Me (inner mind): *sighs* Looks like I'm sleeping in the basement...... again

Slap the creeper! He has no right being on there. But after I've calmed down, I'll get a load of sweets and cake then we'll re-watch Death Note.

I will ask him to help me do my homework :D
L is very smart, isn't he???

i'd scream and trip over my feet trying to run. then, realizing who it is id say, "are te trying to give me a cuore attack?!" then id get up, digita myself and just sit and talk with him.

*poke face to make sure he was real
*scream a weird fangirl noise
* glomp

I would..

-Stare at him for several seconds.
-If he doesn't state his business, I'll ask what he's doing there.
-Poke him to see if he's real.
-Strike an insightful conversation.
-Go for ice cream :D

I would....
1. Scream
2. Grab my katana in my brother's room
3. Ask what is he doing here?
4. And see how it goes from there :D
5. Definitely get to know him, unless I'm in his suspect list...
