Ivor, you forgot the Brass Rule: One phone call and you're out. If you just met the girl: one phone call and you're out. If you've known her for years: one phone call and you're out. If you've just celebrated your 30th wedding anniversary and just got back from driving your ambitious but sexually ambiguous progeny to his new Ivy League college: one phone call and you're out.

That's it and no more.
