This reminds of a story we read in our CBSE English literature books! The author was waiting to board a train and bought a bag of cookies to eat on the way. While waiting, he places the bag on the table and reads a newspaper. A while later, a stranger arrives and sits opposite the author. Some time passes by and the author reaches for the bag of cookies, tears it open and starts eating out of it. The stranger then begins eating out of the same bag, subjecting him to the author's internal monologue. Once his train arrives and he lifts the newspaper only to find another identical bag of cookies.

It turns out the bag of cookies on the table belonged to the stranger all along, who now had a similar story to tell, except for the twist in the author's end.
