I told my supervisor it wasn't personal, and it isn't. I'm not into drama either. I don't care whether or not she likes me. I have always been friendly towards her but she just got all gnarly. I know it is really hard to leave personal stuff at the door. But I have chatted with my other coworkers and it is amazing the amount of stuff going on in people's lives causing them pressure. Most everyone has stuff so no one should be allowed to be a special snowflake.
