From the title 'two thanksgiving day gentlemen story', we can't be certain who these two gentlemen are exactly. However, we can infer that they are the central characters in a story set during Thanksgiving. They could be from different backgrounds, perhaps one is wealthy and the other poor. Or they could both be ordinary people with their own stories and reasons for being part of this Thanksgiving - themed story. They are the key figures around which the events of the story revolve.
We can't be certain who the two gentlemen are just from the title. They could be neighbors who have a Thanksgiving tradition together. One might be older and more set in his ways, while the other is younger and more open - minded. Their interactions during the Thanksgiving Day, as described in the story, would likely reveal more about their identities and the nature of their relationship.
I have no clear information on whether 'Gentlemen' is based on a true story. It could be completely fictional or have some loose ties to reality, but without official confirmation, it's difficult to tell.
