What an excellent thread...and what a hard choice to make, so I'm going to cheat and pick one happy and one sad scene from Ennis and two bitter sweet ones from Jack if that's ok.
EnnisWaiting for Jack's arrival after four years (damn), particularly once he hears the truck and he rushes to the window. I can't help but smile when he does, and it's such a beautiful smile, his eyes full of love, so happy to be seeing Jack again.

Finding the shirts in the closet at Lightning Flat. The build up to the moment is heart breaking enough, but then when he holds the shirts, realising how much Jack loved him, and breathes in, hoping to get even the merest scent of him from them, I just come undone every time. :\'(
JackSinging along to
King of the Road on his way to see Ennis after the divorce. He's so excited, truly believing that this is their chance to have that sweet life, so sure that it's all going to work out

Bobby's birth, when he's pushed out of the picture by the arrival of Lureen's parents, made to feel like an insignificant extra at his own son's birth. So sad, but I guess there's a slightly happy undercurrent, because it's this moment that makes him seek Ennis out by sending the postcard.
