If you seek a happy marriage, I recommend avoiding these activities. Nonetheless, the specificity of this list might indicate that I have real-life experience with some of these, and you'll also note that I am currently married. That indication would be correct. Still, these activities should probably be avoided when possible, just 'cause, you know, we're supposed to be nice and thoughtful and kind to our most special person instead of 1) Nefarious, 2) Thoughtless, or 3) Selfish. As tempting as the latter three might sometimes seem to the most human among us.
-Forget that he/she is coming home late, engage the deadbolt on the door, and fall into such a deep sleep that it takes about 15 minutes of ringing the doorbell and calling the house phone before you wake up and let them in.
-Throw away their toothbrush because it's old, but without checking to make sure that there's a new toothbrush available to replace the old toothbrush, thus leaving them with no toothbrush before they go to bed.
-Give your spouse expert career advice on a complicated issue they're facing at work when you have no experience in their field of work, frustrating them with your 'perfect solution' when all they wanted was a friendly listening ear.
-Use up the last of the toilet paper and 'forget' to put a new roll in the bathroom.
-Force your spouse to participate in a couple's costume with you.
-Buy him/her something for a birthday or anniversary that you wanted and they didn't want.
-Take your spouse on a date and accidentally lock your keys inside the car so that you guys can't get home.
-Lose a point while playing "The Newlyweds Game" at a party by insisting you got married on December 5th when you actually got married on December 4th.
-Utilize your position as family cook to always cook your own favorite foods (i.e. POTATOES! FRIED CHICKEN!) and never cook their favorite foods (particularly anything involving fish, ground beef, kimchi, or pasta, because you don't like those ingredients)
-Wrap up stuff they already own in wrapping paper and give it to them for their birthday. She will probably never forgive or forget.
-'Accidentally' spend $150 on a bear costume on eBay.
-Leave the trashcan overflowing in the kitchen as you head out to work and just hope that they'll do something about it before you arrive home.
I've read before that marriage is a sanctifying experience, a process which is meant to refine our characters, to grow us into better people. I believe it. Have you ever done something that you've later learned is the sort of thing you should probably NOT do, in the interests of a peaceful, joy-filled marriage?
