I've basically said all that I want to say.

However, one other theme that I don't think other posts covered was the film's statement on how fast life goes by.

Before Ennis knows it, Jack is dead and Ennis' chance at happiness is gone forever. At last Ennis realizes that society's approval doesn't keep you warm on a cold night.

However difficult true love may be, if and when the opportunity does present itself, we owe it ourselves to take the chance.

Wishing true love to everyone.
