Long story short, I drove down to visit my sister and my biological dad. Every time I happened to be in town on business, I'd stop in. BIL hadn't met me yet. I pull in and get of of the car, he and a couple buddies are working on an old car and he starts with the, "hey baby girl...blah, blah, how's about, blah, blah..." He told me his name. somewhere in the conversation. I knew who he was, I'd seen his picture. He obviously wasn't paying attention to the fact that his wife had a white-presenting sister. So I told him he must really like to keep it in the family because I was his sister in law. I didn't know till later that my sister was watching it all from the kitchen window and just let him hang himself for her own amusement.
