Your friends shout "Hey, wait for us" and follow you. You get up to the front door and see that it is open just a crack. "We won't be able to see in there, " says Becky, sounding a little shaky. "No problem, " you answer, pulling a flashlight out of your jacket pocket. "Ready?" You push on the door a little, and it opens wider with an agonizing squeak. The three of you peek inside, while you shine your flashlight around. It's a large room, with a staircase leading up on your right. You can't see much, but you can see that there are dust and spiderwebs everywhere. "What's that light?" asks Becky. "It's called a flashlight," you answer. "No, dork, upstairs and down the hall. Do you see it?" You look up and see it, a faint glow. What do you do now? You go to investigate the light. You turn and head for home.
