One of Mrs. Cheech's older brothers used to tease me by introducing me to people as, "This is my sister's friend, KAT" even though he and I were friends in our own right. I saw him as a party this weekend and he said the same thing, just to bust my chops. So I feigned annoyance, then explained to the Pretend Husband how the older bro used to do that to me all.the.time.
Then the older bro said, "Yeah, the other thing we used to say was, 'Oh, KAT's coming to the party? Better get some more alcohol!'"
And if that wasn't bad enough, another friend told the story about how, shortly after a group of us went out for drinks and dinner about 10 years ago, he ran into my dad and said, "Hi, KAT's dad. I just saw KAT the other night." My dad's response: "Was it in a bar?"
Apparently, I had quite the reputation in my younger days (and didn't even know it!)
