You decided that the safest place to stay within the apocalypse was the high school, so you had been temporarily living there.

However one day you hear walking on the bottom floor, nervous, at first you hide within a vent, but then you hear talking "Wow.. It's like frozen in time, I guess no one's been here since the impact" One voice says "Explains why the car was untouched.." A 2nd voice chimes in

As you try to listen closer the vent breaks and you land in front of the 2 guys, their expressions shocked as they look down to you.
