This morning, I walked into my boss's office and I didn't know she had clients in. I froze for a second and walked over to the armoire and pretended to pull a file. I was mortified. Normally, I always knock but the day before the secretary had said that the schedule was clear and no one was coming in. Also the office is very laid- back so my boss has mentioned before that knocking isn't necessary. Yet I was mentally cursing, "crap. Crap. Crap."
