Rat-a-Who-ie

So at 12:30am sunday morning, i was chilling at my computer desk in my dorm room, when out of the corner of my eye, I saw something gray climbing down the wall. I look up for a split second and pushed myself off the table and jumped up screaming....it was a RAT!!!

Yes a rat. but after i jumped up and was screaming, it disappeared. And then i started to move my stuff around and then it climbed the wall, crawled on the ceiling i got on top of me and my roommates closets. I called the EMERGENCY maintenance and they said they couldnt do anything till monday......SOML(story of my life)
