You’ve met someone. Ask him if he has a business card (so you can google that shit and make sure he doesn’t have a wife…or worse, a LinkedIn profile). When he asks for your number, just give him your email address and explain that you have a smart phone so it’s basically the same thing as calling you. Pretend not to hear him if he tries to point out that it’s not the same thing at all. Shake his hand to see what kind of handshake he has. Then use some hand sanitizer because he could have been masturbating or doing that tucking-his-boner-into-the-waist-of-his-pants-thing in the bathroom. Offer him some so that you don’t hurt his feelings.
