When you feel so unbelievably amazing about somebody that love doesn't seem to do it. It's the greatest feeling in the world, and you'd take absolutely any opportunity to be with the person you lurve. Staying up late at night thinking about them, staring into their eyes to escape reality, longing to hear their laugh, see their smile, feel their hug. You can't compare lurve to anything else, so unless you lurve someone you can't imagine the feeling. If you lurve someone, you know.
Mark knew he lurved Stephanie the first time they met eyes...he couldn't look away.
