Why doesn’t it ever last?

As is the case often, whether for better or worse, yesterday evening did not go as I planned. Practically everything I set out to do took longer than expected. I decided to go to bed rather than post here.

The tiny quote below is from a story where the character’s wife has just died (remember how I’m mean to all my characters?). It strikes me today that it applies to so many different relationships that end for so many reasons.

“We were happy together. Why doesn’t it ever last?”
