I'd like to meet the last man on earth and ask him how loneliness feels. I'd like to meet The Mercury Seven, the original astronauts, and ask them what possibilities lie ahead. I'd like to meet my ancestors and compare their real-life experiences to the accounts documented in history books. I'd like to meet the me when I was 6 and ask her what she wants to be when she grows up. I'd like to meet the me when I'm 80 and ask her if she has any regrets.
