Relationship: What makes it work?

Is when you two can act like lovers & best friends.
It's when you have more playful moments than serious   moments.
It's when you can joke around, have unecpected hugs & random kisses.
It's when you two give each other that specific stare and just smile.
It's when you'd rather chill inside to watch movies, eat junk food and cuddle than go out all the time.
It's when you'll stay up all night just to settle your arguments and your problems.
It's when you can completely act like yourself and they still love you for who you are.
