Say out loud in the coolest possible voice “time to take out the trash” then proceed to throw them in said trash.

Console Silver Spoon. Boot Diamond Tiara in the head.

@Pinksy  

Bring them in, comfort them, try to figure out what happened.
 
Then, confront the strong possibility that I might have finally gone off the deep end.

@Pinksy  
Good sir, that comment has won.

@Crowley  
Yeah, this guy bothered to find the image. See what a good example he is to the rest of us? Good on ya, mate.

Call a psychiatrist because I think I’ve just gone insane.

Quickly invite them in and help them feel better.  
Dont get me wrong, I hate them aswell, but im not gonna be a total jackplot about it.

Let them cry until I feel guilty, then help them.

Let them cry some more…

Go away! I don’t care what happend to YOU but what it was you deserved that!

Call their parents. Or a social worker.

Scream, shut the door, call my parents, tell them I just saw something that shouldn’t be possible, then get drunk, choke myself until I pass out, check if they’re still there, if they are, probably kill myself.

Hape.

Just say “Nope” then shut the door -..-

Point and laugh.

I’d take them in and do everything I can to help them.

Help them begrudgingly.
