No. Because it tells me you aren't whole. And I need a whole person. Not just pieces. Unless, like something happened to both of us and I only have legs and you only have arms. And then its cute and funny. :D it would be 'our little joke'
That's the biggest bullshit line. No one completes anyone. The only completion is time, when you discover that new truths learned help you to remember what you knew as a kid before the world made you forget.
No. It's a cheesy line. Also, someone should already be complete and not depend on the other person to make them whole. That means you are dependent on them.
