If you are such hypocrite talking sarcastically in every speech you giving, I am sure No One would like to entertain you.
Ppl love to complain, "Why they don't like me?" Sometimes, you are just unlucky being together with a group of "unclick" people where unfortunately there is a person who has a strong influence power dislikes you. Then that is your luck. I met this before (but I never complain, I tried to fix). And trust me, that person would pay this price. The word of "forgiveness" doesn't really exist in my dictionary, to enemy.
Another reason is, the problem lies on you. Attitude is always the issue, especially in this case. =P Lunch break is really precious moment, be wise.
