Dont be scared. Prepare your house home alone style. Put legos everywhere and ALWAYS have a loaded gun in your pocket. When they enter say some bs like "I like running into volcanoes full of dolphins" and while they're trying to figure out what the actual fuck you mean. Kick em in the balls and shoot em. Or you could pretend you speak another language while they try to understand you. Take them on a tour and lure them towards the basement entrance. While they're looking downwords towards the basement drop kick em in the basement and lock the door with whatever you have. But if they come in groups just... Invite them to a tea party.
BAM! Close enough. *gets 200 XP*
