Your colleague was mentally ill person and everyone at the base knew about it perfectly well he did not do anything too strange or frightening, he was just too silent and scared you with his gaze.. one evening you were instructed to give him a folder with task reports, you did not want to delay this, so you immediately went to his room you quietly open the door and see this picture in front of you: a man is sitting on the floor with his knees pressed to his chest, looking at one point with an empty stare, an empty medicine jar lies next to him you also hear him pronouncing in a half-whisper:
"я больной сука я больной... я не ручаюсь за себя бябябябябябя я слышу голоса в своей голове.. они говорят бебебебебебе.."
It seems the poor guy has run out of pills..
