I hate when people guess what word I'm going to say and finish my sentence or say the word at the same time I say it. I have a coworker who does this and I don't know how to tell her to STOP IT! I know what I'm saying, it's not like when someone is reaching and trying to remember a word, there's no pause or anything. It's so irritating.
I also realized on Sunday that old/new supervisor at part time job does this too. I don't know if I can handle two people in my life that do this.
