text: First, you must realize that she has placed herself in a position were she is not only your boss but also your friend. She still has to maintain a certain level of authority over you and that requires her to reprimand you.  You should discuss with her your confusion as to her sudden change in tone when this has been a common scenerio between the two of you.  She may have just had a bad day and your comment was "the straw that broke the camels back", and she may apologize first! Other than that you need to discuss with her your limitations in this area. You need to understand that just because you are friends you can't use that to your advantage, nor be angry with her when she has to do her job.  You are the employee and she is your superior. As hard as that is to deal with, you must. Talk to her on nuetral ground (home, dinner, etc.) If you discuss this with her at work, she is still in the authority mode. Good luck!
