Yes, absolutely. I certainly don't think either Ennis or Jack would have ever thought about their relationship in the context of something as conventional as Valentine's Day. However, the more I actually think about this the more I find myself thinking about the ways in which both Ennis and Jack did demonstrate romantic tendencies (maybe even despite themselves).
Yes, I agree. I just can't see them exchanging frilly valentines, though. Or even manly cowboy valentines!
Because they wouldn't want to risk anything that open.
But I can imagine them pining for each other that day.
It is sort of interesting to note that the two holidays that are represented are so solidly nationalistic/patriotic/American. I wonder if there was an underlying reasoning for choosing to depict the 4th of July and Thanksgiving rather than, say, a religious holiday (or something that might be more universal)?
I've always assumed the 4th of July was a deliberate attempt to play on the "cowboy as American icon of masculinity" myth and its ironies in Ennis' situation. Also, I think there are deliberate parallels between the two sets of holidays. We don't see Jack celebrate 4th of July per se, but I think we can assume the Jimbo incident happened somewhere around that time.
So in the earlier July 4 (or thereabouts) scenes, both Ennis and Jack have their masculinity challenged or questioned in some way. Ennis "wins" by beating up the bikers and Jack "loses" by getting rejected by Jimbo.
In the later Thanksgiving scenes, once again both men have their masculinity challenged or questioned. This time the outcomes are reversed; Ennis attempts to solve the situation with a physical fight, which he loses. Whereas Jack "wins" in a war of words when he tells LD off.
I think the parallels are deliberate, though I'm not entirely sure what it's supposed to say. Why did Ennis win at first, but lose later? Why did Jack lose at first, but win later? Was the ultimately greater effectiveness of verbal rather than physical conflict intended to make a point?
