So, I have this very good friend whom I love dearly. Said friend has passed gas both times I've seen her this week. This is definitely breaking new ground for us. She is a "lady" in every sense of the word, so I know it's completely accidental. But, I honestly don't know how I should react. Thus far, she's said, "excuse me" and I've pretended like nothing happened.

What would YOU do? And what might Miss Manners suggest (in case the answers are different)?
