Humor is a good way to say "hello"...I don't think a "guide" is worth thinking of, as it is only an "opinion" of the person whom wrote it, and how would you know that they had any success following their own words? I had a small sort of like stuffed animal that was a lizard. It was green with black looking scales on it, and had two small shiny eyes. In total it was maybe 4 inches long. I would carry that in my pocket, and to have a bit of wicked humor, well, I would ask a Gal if she wanted to "check out my pocket lizard"...and just as the Gal would about go ballistic, I would pull out the little stuff animal lizard and with a smile, say, " here ya go"....it normally would make a Gal laugh, they would make comments about things, and I met a lot of fun Gals with that lil pocket lizard. Humor works, try it, no one ever gets too mad at someone being funny.
