Tick Tock

I fell asleep in my bedroom in Colindale last night for the first time in a month. When I went to bed, I didn't even notice if my alarm clock was in my room, let alone running. When I first awoke, I looked for it to find out what time it was. Once I located it, the sound of its ticking seemed to boom throughout the room, preventing me from getting back to sleep for 20 minutes. Yet, the clock was in the exact same place it had been all night.
