Tulog (Asleep)

I was with my wife in an emergency room. It was nothing serious, she was there for observation. Anyways, we had to stay overnight while we wait for the laboratory results. It's an emergency room, so it was difficult to sleep. I doze off now and then, but most of the time, I was awake. Beside us is an adult male with a companion which appears to be his son. The adult male is lying on his bed while his son, is sitting near his bed, sleeping. Suddenly, his father with a loud voice said: Boy, tulog ka? HUUUY! TULOG KA?! (Boy, are you asleep? HEY! ARE YOU ASLEEP?) Of course, the boy said no, at least not anymore. :)
