Hindsight is always 20/20, or is it?

I need to get this out of my system - I believe in positive attitude, that your thoughts control your mood, and that negative attracts negative. But I want to share this and ask for your opinion. And then I'm going to 'let it go.'

Today I went to a community event with a friend. She seemed to know just about every other person we ran into. She gracefully introduced me to those whose name she could remember. As we joined three friends of hers at a table, she introduced me by name and then told them that I owned Sandy's Stuff.

The man at the table couldn't have cared less. I knew one of the women who used to (very rarely) come in to the store. The other woman (64-year-old professional woman) said, "What's that?"

I told her it's a woman's consignment store.

Then, and you've got to believe me here, she immediately turned up
her nose and said (quite loudly), "A big g -- d--- garage sale!"

I was speechless. I'm sure my jaw dropped open. I said nothing. I couldn't think quick enough. My friend simply said something like, "Well, Sandy has nice things in her store." And their conversation proceeded on to another topic.

I still said nothing. After another minute (at the most), I got up and walked away. When my friend caught up with me several minutes later, I asked her how she knew the woman. She responded that she was one of her best friends.

But the things I later thought of to say:

"Do you kiss your mother with that mouth?"

"Do you know you said that out loud?"

"How rude!"

But I said nothing. My friend Debby is probably proud of me thinking that I took the higher ground - that I didn't stoop to her level (from which I would have had better leverage to kick her in the a--) - but I actually said nothing because I was so shocked, that no words came to me.

What would you have done? What would you have said? Would you think a little differently about the friend who introduced you?
