Two Times One

What evidence do you have to support your theory?

- Well, not much really, just a few apparently unconnected facts. First, remember that Dr. Evans and I used to bet on the possibility of time-travel. He was against its existence if you remember. Second. Do you remember I used to buy a weekly lottery number with the same three ending digits, 347? Well, the past weekend I couldn’t. Why? Because the only ticket with that termination was bought by someone else before me. Even after the ticket vendor used to reserve that numbers for me because I asked him to do so. The ticket vendor told me that some old guy, 70 or something, bought it at 10 times the usual ticket price. Guess what? The ticket number I was going to buy resulted to be the winning one.

- Well, well that sounds very unusual but coincidences do exist. And you know how old guys tend to act quite strange sometimes.

- Ok, that could be a possibility. But let me show you this. I received this postcard from a Caribbean island.

- let me read it… "You will win the bet my son of a gun. But I have already paid you. 20 years from now" Weird! And it doesn’t say who sent it to you.

- No, but I bet you who did it.
