The actual letter from the head of the project in the company engaged in programming - all of the other ways to reach out to the team did not work ...

Lord,
 the one who leaves the room the latter shall turn off the lights, close the windows ventilyatoryi.
 How do I know you're the last:
 - In the room no one else
 - Are you all goodbye
 - The neighbors did not respond

How to determine that the light is:
 - Look at the ceiling
 - Translate gaze from the monitor to the keyboard
 - Flip the switch

How to determine that the fan is turned on:
 - Blowing
 - Rotating propeller
 - To put a finger (not recommended)

How to determine what window is open:
 - To hear the sounds of the street
 - Blowing
 - Fresh (stale) air
 - Lean (slightly)

If not taken into account, write to the conference. Shit.
