Laugh at them and point.
Snarl deepy and walk away.
Giggle but playful and run over to help then up.
Be the one trowing the ball.
Walk over serously ask if they were okay and then laugh together.
Wring you hands and stare at the door.
Go through the stuff finding stuff you want to keep for yourself.
Go out and join them to bring them back home.
Go out and join them and have some fun.
Go do some homework wairting for them to come back.
A man dressed up trick or treating with his child.
You don't care whats in the bag the man looks like a tastey treat to you.
A man maybe going to come to your house next.
Stare at him carefully deciding weather hes human or not
Take it anyway and thank them
Say "let me put it away" and then grab a trash can and throw throw the gift right in the trash in front of their face and then say "there".
Look very exsited and put it some were where it will be clearly seen then once the person leaves put it away in safe keeping.
Smile and thank them. you don't really like getting girts anyways.
Look them in the eyes with an apoligetic look and say sorry you don't want it.
