That I will open the door
Pizza because it can be slipped under the door.
Hodor
Alexia again to open this door!
Because there could be an Italian dressing inside.
You wouldn't believe me if I told you.
Because they don't believe in higher powers.
Knock, knock, knockin on Heavens door
A Jehovah's Witness.
Someone who shows up to your door for no reason.
