We have a special room in the laboratory - growth room, for growing plants. The lighting is artificial, there are automates - at 23:00 the lamps turn off, at 7:00 in the morning are turned on. We have been doing this for 4 years, by word.

Recently, our guard (the university guard) “has been vigilant.” It turns out, they noticed (for 4 years) that someone lives in our lab. Who shuts off the lights at 11 p.m. and turns on at 7 p.m.? For several days, the guards were tormented by this question and even tried to guard the mysterious settler. They even tried to break the door at night. They decided to first ask my boss if there is anyone living in the lab. We did not decide for a long time, as our boss is known for its horror, but we still came with their boss. What he replied to them (Sh - the boss, O - the chief guard):

O O. Someone lives in a laboratory.
