Hypothetical situation.
Say one evening/night you are drinking at a couple of friends, the house you are in is located a little far away from the city, it is somewhat of a farmland, still a couple of houses are nearby.
The house you and your drinking buddies are in consists of a big room upstairs
and a kitchen and bathroom downstairs. The drinking and partying is done upstairs.
The situation is this: You are all sleeping after that night, you wake up and go to the bathroom
to do a number 2, however, the bathroom light does not work, no biggy, you will poop in the dark.
You also brought your smartphone and you lock the door..
2 minutes later you hear the front door open, somebody runs up the stairs and starts killing all
the people with a knife, you hear all their screams of terror and their begging for mercy.
After several minutes it stops, the murderer runs off, into the night.
What do you do while you are hearing them get killed? Or do you wait until the murderer leaves?
Remember you have a smartphone with you, and the murderer never knows you are there, since the light does not work.
