11. Get involved with his extracurricular activities. It’s not all business deals and power lunches with a Wall Street man. Even he likes to let his hair down occasionally in his high-rise offices. The Wall Street man works in a very competitive, stressful environment, so when you find out that he and some of his other fellow Wall Street men are stepping away from watching Greek debt news to paste up “We Are the 1%” signs on the windows adjacent to their cramped cubicles, offer to help them with the lettering, tape, and glitter.

12. Be open to his mood swings. Even the most successful Wall Street man will flub a credit default swap now and then. He is only human after all. It is important to remember that when he does his job well, many lives elsewhere could be ruined, but when he does something wrong, there is a fair chance he will get a stern finger-wag from his superior, and will in those rare moments feel vulnerable and unloved. The Wall Street man will often try to hide this pain, but you should remain by his locked bathroom door for however long it takes to coax him back to his usual level of self-confidence.

13. The Wall Street man may occasionally chase after you with a chainsaw. Every relationship requires give and take, so it’s important to remember that you may find yourself in the company of a Wall Street man who intends to commit grievous bodily harm against you. Don’t get upset by this. If you make a point of asking him before dinner about his rare Hungarian knife collection, he may instead only describe their price and provenance to you, and leave them in their ivory case this time.
