No matter how good your heart is, eventually you have to start treating people the way they treat you. 

Listen, I know a lot of times I advise everyone that when someone treats you like shit, and doesn’t give you the time of day, to back off and don’t ever speak to them again. But sometimes that’s hard. Sometimes there are situations in which you HAVE  to see these people on a regular basis. When this type of shit happens, and you have experienced a certain individual that’s treats you like crap and embarrasses you in front of others, you have no other options than to treat them the same way. You have to defend yourself. Why is it fair they can do it to you, but you can’t do it to them? Doesn’t make sense. Now I wouldn’t go ahead and risk your job or career but if they give you shit, feel free to give it back. Sooner or later the entire company will start to hate this person and you’ll be in the clear. DON’T be a human punching BAG. Give it right back to that fucker.
