late night scare

so theres this cat. at least i HOPE its a cat. that groans always in the middle of the night when i happen to be asleep. nay, when EVERYONE happens to be asleep. and i say groan and not meow because meow is supposed to indicate a cute sound. but NAY, its more like a dead baby oofing its last breaths. so the first few nights when i heard it, i was like, wth!? then i calmed down because panicking almost always makes you do dumb things and makes the situation ten times worse than it really is, and since i have a semi balcony that anyone can climb onto, i figured i could be in some danger. at any rate, i calmed and lay really still, and strained my ears to listen to that horrible sound. at some point on the tenth groa/meow, a certain tenor of the sound betrayed that it really was a cat....mystery solved. whew.
