You go outside again and walk over to your neighbor's house. Instead of ringing the doorbell, however, you walk up to the gate and shout, "Hey, Isabel! Can I come swim?" She shouts back, "Um, sure, Kelsey! Come in!" You open the gate and walk in. Suddenly, you realize that you forgot a swimsuit. You ask if you can go inside her house to look for one, and she says yes. Once you go inside, you notice her parents aren't there, and soon realize that they're on vacation for the weekend too.
