No Respect

Here's a snippet of a conversation between my brother-in-law and a co-worker:

Co-worker:  "...I work at this place called Lightborne"

Brother-in-law:  "...oh yeah, my brother-in-law works at Lightborne too"

Co-worker:  "Really?  What's his name?"

Brother-in-law:  "I don't know."

 

So through a description of my person by the co-worker, my brother-in-law learned my name.

Ok, it's not like I just recently married his sister (it will be 13 years this June). It's not like she's his half-sister or step-sister or something. They are blood relatives. He was around when I was dating her back in '93. He was at the wedding. He put a crown in my mouth last year. How is this possible?
