I made a barter on craigslist in which i was given a stamp and an envelope in exchange for keeping a bottle of coca-cola with me for a year.

you can see the exchange here:

i am going to new york for a month, though there is a chance that it might be for longer.

am i obligated to take the bottle with me?
