OK, forget about kissing for a second...(I know it's hard, once you've
started...)
What about the "toothbrush a day" habit? That's kind of...odd. Do you
suppose he just did it so that people who knew him well would think that
he was, well, a "little weird?" (He strikes me as the type who would
like to keep ~everyone~ guessing, but highly intelligent. He knows darn
well that that's a bunch of nonsense with the toothbrushes.)
I have my odd habits too, which is how I know he knows it's an odd
habit. He almost seems to take pride in it.
Of course, if you have a toothbrush for every day, it gives it plenty of
time to dry, and extends the life of said toothbrush.
Of course, of course, you would have to have a specially built
toothbrush-holder, with a slot for each day...
