" You do what you have to do to give people closure; it makes them feel better and it doesn’t cost you much to do it. I’d rather apologize for something I didn’t really care about, and leave someone on Earth wishing me well, than to be stubborn and have that someone hoping that some alien would slurp out my brains. Call it karmic insurance. "
