The Meaning of Obligation

Broke a pencil during meeting today. I can't stand his nonsense anymore. He actually told me to smile knowing that I'm horribly stressed n pissed? "SMILE! I like to see you smile" Damn! I'll smile when I smash your head you old mean ass. Now after harassing my friend and family not to mention bombarding my mobile, he tells me it's not an obligation for me to answer or even read those messages when I'm on leave? Huh? Tell me something I can understand. Perhaps I don't understand geniuses. And what now? I'm supposed to explain programming codes again? To a person who thinks insertion of data into the database means creating a new database. What does he mean by flow? There's no flowcharts for this! Flowcharts show the flow of the process, not the codes!! Flow, flow, flow! Can somebody please get him off my back and ask him to only come back to talk to me until at least he's gotten a diploma in IT. Ok. So am I still obliged to SMILE? My patience is wearing off.
