I hate opening the doors to trick or treaters. I hated it even more when I had to accompany my younger brother at trick or treating last time when all I'd wanted to do was get on with my studying and be in the warmth.
I find it to be overwhelming, especially when they yell, "TRICK OR TREAT!"
It's mean, I know, but all I want to do in response is slam the door shut and hide. I live in London on a packed road so I have no choice.
