Time loop
What would you do if you met your future or past self?
Max and Paul are having a beer, when Paul suddenly points towards the other end of the room.
Paul: Wow, look! That guy at the bar looks just like me in 20 years!
Max: Totally! Maybe it is you! We're in a time loop!
Paul: Should I ask his advice? What would my older me want to tell me?
Max: Don't bother. You don't listen to anybody anyway, not even to yourself.
Paul: Does he look successful? Does he wear a ring? Some status symbols?
Max: Who cares? You can worry about that at his age. For now, let's just drink on his, err your tab!
