hallways the sun

So, it's just past 4 a.m. and my neighbours appear to be wandering around the hallways; sneakily, no less. They do this most every day it seems. I'm not sure which ones are doing it, but it does appear to be more than one. They seem to know each other ... possibly in the Biblical sense, given the average amount of stealth that appears to be going on. Maybe I should play some stealthy sneaking around music for them, like the sort of incidental stuff James Bond gets when he's sneaking around some place he's going to get caught sneaking around.
