Horrified.

   I think there just might be a mouse in my room. I heard the skittering in the right hand far corner of my room, and Heidi (the watchdog of the room) was sniffing at the shelves there curiously... So I am armed to the teeth with a shoe, the BB gun, and a knife. The mouse'll never make it out alive if I have anything to say about it, by george!
   Mind you, I have nothing against mice... Just when they sneak up on you. You never know what the little vermin might do- it could gnaw a hole in my hair as I sleep! Filthy little thing. Though I'm considering catching it in a hat and keeping it.
  Provided, of course, that there IS actually a mouse in here. I could be imagining it, or it could just be an overgrown, mutated housefly trying desperately to escape the doom known as my bedrooms shelving. I should clean that. Though I'm afraid to, now, obviously. Due to the mouse. That may or may not exist.
   I blame mom fully for this. She insisted on removing our old television from the stone ages and putting in a sleek futuristic one in its place. Of course, our house is one with a hole in it for the television, and the old TV is so huge that it took up the entire space, so when she moved it she found practically an entire ecosystem back there, complete with waterfalls and specialized organisms. Okay, not quite, but she did find a mouse. She probably made it mad by invading it's abode, so it told all it's little mouse-friends and they've made a vendetta against us, and are going to start punishing her by murdering her daughter as she sleeps innocently. I'm sure.
  Wish me luck against the vermin army.
   I knew we needed a cat.
Later:
  Well, now it's coming from the shelving on the left. Oy vey. There must be a bunch of 'em! Because I've had my eye glued to the right for the past 15 minutes, and there's no way for it to get to the left without going in front of my line of vision. Of course, it's very near the garbage bag that contains my prom dress. If I wake up tomorrow and find a hole in that dress, I will personally find that mouse and make him rue the day he was born.
  I'll keep ya'll updated...
Even later:
   I survived the night with little drama. I heard some scratching, but it's amazing the nose that an obi will make when smacked against the curtains hiding the mess in the shelving (it was late and it was the first thing I grabbed, what can I say? At least I didn't try to shoot it with the BB gun). Haven't heard anything else... Of course, it could have just been the dog moving. Needless to say, I think I almost gave her a heart attack... Seeing as how I brutally beat the curtain with a karate belt, right next to her head, waking her up and throwing her into a frenzy. Still. The rat poison goes out tonight!
   Later:
   It just ran across the floor!!
  What the heck do you do with a mouse once you locate it?! I am currently perched up on my bed with my BB gun trained on the inner workings of the shelves (I managed to remove the curtain without giving myself a heart attack). If that mouse shows itself, it'll be sorry...
