My own definition of karma is slitghly different. It goes something like this:
Your name is Mary, you suck. You are part of a major group project in your Master's class. Your partners are two very nice hardworking people. You, as stated earlier, suck. You screw up the project and presentation by doing, well, nothing but sucking. You are stangely ignorant or oblivious (must be used to it in all aspects of your life by now) of your sucking.
Fast forward a year.
You, still sucking, interview for a position at the office one of your nice hardworking partners works at. You are friendly and try to be nice with him in front of the people you are interviewing with. You suck at it. You interview (presumably suckily) and leave. The people you interview with decide to turn to your old partner to see what he knows since you made it obvious you knew him. He makes it obvious to them the details of your suckitude. The next day you are officially a "negative" for the job.
Now that is karma.
