Having a sense of humor in a relationship is important. You have to be willing to laugh at yourself and to laugh at your significant other’s jokes (even if, and especially when, they’re not funny). The first time you let a fart fly in front of your S.O. is a time when you need to laugh at yourself. And when your S.O. teases you about that fart the next day, you need to laugh again. If your S.O. is one of those people that has the running joke “what do you want to eat?” and answers “food” every time, then laugh every time.
What’s the worst that can happen? Your S.O. will feel good that they made you laugh, and you will get an increase in endorphins because you laughed, which will then make you happy. It’s a win-win.
