I have a friend that is a close talker...he is part of our card playing group, and is also a member of my sportsman club...and I use to work with him at a factory.
We've been acquainted 35 years...I say acquainted, because our friendship has had it's ups and downs...he can be a real jackwagon sometimes.
Anyway, when he has a conversation with you, he likes to get right up in your grill. I asked him once why he does that, he says he likes to be able to smell what you've recently had to eat.
After that, every time I knew I'd be in his presence, I'd make sure I have extra raw onions on a hamburger...or some extra garlicky dish..Hey I like onions and garlic anyway. Because, I figure I gotta give him something to smell, right.
These days, I avoid being in his company.
