((((((((Pootypoo))))))))) Sometimes the most natural thing to do, and the best for you, is the thing you can't do because of things like social norms or stuff like that. Do you think just mentioning that you felt hurt by that type of comment, sometime when you can distance yourself better, might help? It might help your manager if she knows that YOU are also aware of your slips of speech and are bothered by it.
Then again, you know her best, dear. Huggs!
