A happy couple is one that laughs together. When people say laughter is the best medicine, they mean it literally. Laughing releases serotonin in your brain and lifts your mood. And it's infectious! It can bring an argument to a standstill, and it can dry tears and drive off sadness.
Life is too short to spend the whole time serious, and nobody wants to spend their days with a stone-faced spouse anyway, so take the time to sit back and laugh with him. That doesn't mean you have to laugh at his terrible jokes, just tell him a better one. Bask in the absurdity around you. The world is a strange, crazy and wonderful place and there's humor everywhere if you look for it. Don't be afraid to play the clown when he's down and know how to put a smile on his face when it falls off. Who doesn't love the person who makes them laugh the most?
