Tommy : What about the boogeyman? Laurie : There's no such thing. Tommy : Richie said he was coming after me tonight. Laurie : Do you believe everything Richie tells you? Tommy : No. Laurie : On Halloween night, it's when people play tricks on each other. It's all make-believe. I think Richie was just trying to scare you. Tommy : I saw the boogeyman. I saw him outside. Laurie : There was nobody outside. Tommy : There was! Laurie : What did he look like? Tommy : The boogeyman. Laurie : We're not gettin' anywhere. All right, the boogeyman can only come out on Halloween night, right?...Well, I'm here tonight and I'm not about to let anything happen to you. Tommy : Promise? Laurie : Promise.
