One of my co-workers got to be a close friend of mine. Then she decided that I was advancing faster than her and sabotaged my job.
Oh that is so selfish. Did you try and get back at her?
No, I cut ties because it wasn't worth it to give her the satisfaction of a fight.
Thats great, says a lot about the type of person you are, in a good way! I probably would've gone for revenge knowing myself.
