"A boy's best friend is his mother." Anthony Perkins as Norman Bates, Psycho
Happy Valentine's Day! Don't marry a psycho.
There is no decision you will make in your entire existence that will have a greater impact on your quality of life than who you choose to marry. Don't treat it like an apartment you're renting or a job you can quit. Give this decision the weight it deserves and struggle with it.
Your choice of spouse affects all of your relationships: familial, professional, lifelong friendships and tangential acquaintences will all bear witness to the lunacy you've chosen to bring into your world. If you marry someone who doesn't bat an eyelash at approaching a waiter on a smoke break to tell him that, if he ever offers to grate parmesan on your salad again, he'll break his legs... imagine what someone like that will do if he finds out your boss literally patted you on the back when you landed a big account.
