Occasionally when I get the blah’s, I’ll cheer myself up by taking yesterday’s newspaper and putting it on top of the other papers in the box on the street corner. Then I wait around whistling, waiting for someone to buy it.
When they do, I go up to them and say “I’m here, just like I said I would be. Now do you believe me that time travel really works?” When they give me a strange look, I say “Look at the date on the paper”. When they are confused, I say “So this is your second chance. I saved your life once already. Don’t make the same mistake tomorrow because I won’t be there with the time machine when that knife comes out of nowhere.”
Then I walk away all cool.
