OK, I just called her for further clarification.
I asked if the YMCA/seafood chains are anything like Long John Silver's, but she just let out a *giggle* and said that she loved Long Johns. She asked if I'd still be hungry for dinner if she had crabs, and I told her that I've had a lot of seafood in my day and thus am no stranger to crabs.
I completely understand what she means, though: if somebody is eating something gross at the other end of the table, it can completely eliminate your own appetite.
Well, time to get ready. I'll bring my NRSV and hopefully we can discuss a few passages.
