"there comes a time when a man finds that he can't fall in love again. He knows that it's time to stop. I don't belong on your ship. I belong on this one. This was my home. This is where I had a purpose. But it's not real. It's just a computer generated fantasy. And I'm just an old man who's trying to hide in it. Computer, shut this bloody thing off. It's time I acted my age."
Montgomery Scott - Relics.
