“If someone lies and says they are dating someone or they are moving to another town soon, you don’t feel rejected, because it’s no longer about you… So I guess what I’m saying is the next time someone asks you out and you aren’t interested, the nicest thing you can do is write back: ‘Sorry, can’t do dinner tomorrow. I’m leaving on a secret mission with the space program! When I return to earth, I will have barely aged at all, but you’ll be seventy-eight years old. I just don’t think it’s a good time for me.’”
