Technique Tuesday Question: Endings

I want to know your thoughts on writing endings of a story. They KILL me every time. like those last scenes where you wrap up all your story threads and show the new normal for the characters (as opposed to the normal at the beginning of the book.) I only managed one ending I really liked, and that was for Plus One. I STILL cry when I read it.

so what sort of endings have you written for your stories? What's your favorite ending from a story you've written? what sorts of endings do you like to read? do you know the ending at the beginning? (I did for Plus One, and I think that's why I like it so much.)
