AM1776, apology is accepted and issue is buried. My error (as I have been advised "backchannel", i.e. by my my wife and others) was in making a grammatical jest -- engineers and grammar can be dangerous combination. I am sorry.
Your post was funny -- I've heard an Anglican variation of it, though I don't recall the particulars. Maybe someone can post it here... (and ping me, please?).
If your sister has any questions about matters Episcopalian/Anglican, do aim her in my direction and I'll do what I can! I am no expert, but I learned quite a bit from my ping list predecessor Arlin Adams, RIP, and have many references.
I know all about engineers, I am married to one. My error was in not reading close enough and scanning over in a hurry.
You know how it is with family, it is alright to fight among yourselves, but let someone else come into the fray, and watch out.
