Don't Angry Me !!

It was normal working day for me. Started as usual at 4:00 AM. Worked whole day more or less as per plan. Ahh jaa... Its badminton day today. I called my badminton partner around 17h and decided to go together to badminton hall. My iPhone was with me but not ofcourse during game. So there was no way I could see any phone, mails or messages.
After the game, in changing room when I checked my mobile I saw strange mail, one of the master student wrote me personal mail and asked whether I took his book from the office just because I have access to the room where he is seating. Come on !! Are you kidding me. It was not at all cool. But I controlled my emotions. Went back to office and then to this room where I found his friend working. I politely informed him that I have nothing to do with this book and requested him to inform this student. Then I came back to my office wrote official reply to his mail. As soon as I sent my polite reply. Somebody suddenly rushed in my office. It was the same guy not in good mood (Well, I completely understand this). He asked me about this book in raised voice , even after his friend informed him that the book is not with me. I started to loose my temper. But was still in control.
(Thanks to meditation practice). Then in the same voice he started that you are NOT receiving my call, I have been to your office and you were NOT there. Excuse me !!! Its my mobile and it is for my convenience and not his... Then I requested him first lower the voice and go out of my office but he tested my patience to the limit ... And then boooommmm .. I proved that I am NOT buddhas. I raised the voice used all possible 'f ' words and hold his shirt and dragged him out of my office. Took him to his friend and was discussing with his friend ... then all possible arguments were there... but I told his friend that I am NOT interested in talking now because this guy is NOT in mood of discussion he is arguing always...
Now while writing this blog I justify my behaviour with following point...

1.  Even if I have access to the room he is seating he shall have wrote to the group mail and NOT personal mail.
2. He should have discussed the points in lower voice.
3. He should have knocked my office door before entering the office.
4.  He should know that I am PhD student and he is master student and I need NOT to inform him if I use his room
5.  He should have not blamed me for not being in my home and/or not receiving my personal phone.

Even if all above mentioned points are in favour of my behaviour, I now regret my action :( 
(Afterwards, I have apologized for my behaviour in group mail without forgetting to condemn his unprofessional misbehaviour !)
..but then I convinced myself that it was "your reactive response to this person's misbehaviour".

I do like Gandhi and his thoughts but once in a while you should also have to be NON-Gandhian.
