...I could tell you that I miss you, but I don't like that expression - "I miss you" is usually when you're bored, but my life is full of different events.
"I miss you" is not the same.
It means - a person is just a missing part for a happy picture of the world to be complete.
No, I'm perfectly happy, but you are my world.
If you asked me what I feel when you're not around, I'd say.
"I'm hurting without you, " and that would be true.
No matter how busy I am, captured by time, people and events, no matter how happy I am, something inside there impossibly aches for you...
