October 31st.

Accepting a bet that you can stay a whole night inside a haunted house (on Halloween) is very easy when it's daylight and the sun is shining from a clear blue sky.
The doubts about whether this was such a great idea in the first place, begins to sneak up on you as the daylight slowly fades on October 31st.

But here you are. On the street outside the iron gate looking at the graveled path that leads up to the haunted mansion, wondering if it was such a good idea to accept the bet that you could stay in the house till dawn.
