'Uncle Albert and Aunt Mandy were nice enough' I thought to myself. I don't know what all the fuss was about them. Sure they're a little weird...but who isn't. Although there is one thing itching at me....'Should I be nosy and ask' I question myself. Eh why not.? "Auntie...Uncle.? Can I ask you guys a question.? "You just did kiddo.!", jokes Uncle Albert. "Sure honeypot. What is it.?", says aunt Mandy. Here goes..."Don't I have three cousins.? I only met two..." I watch intensely as both my aunt and uncles' faces visibly pale. "Erm..yes you do. But your cousin Jimmy isn't very...nice to say the least. We keep him in his own little house in the backyard, which you are forbid to ever go into. We are serious about that rule Katherine.! Do NOT go into the backyard keep your distance from Jimmy at all cost.!" Warns Uncle Albert. Well that sucks I really want to meet him for myself now. Curse my curiosity.! I mean he can't be THAT bad can he.??
