Casual relationship

So, a casual relationship is like when you have a friend that you sometimes play with or hang out with, but you're not boyfriend or girlfriend. You can still have fun together and enjoy each other's company, but you don't have serious feelings like you would in a boyfriend/girlfriend relationship. It's like a play-date, but for grown-ups! Just make sure you both understand that it's not a serious relationship, so you both know what to expect.
