Secret letter.

Things will always get better.

A boy gives his girl a letter. 
Says don't open till the day I die.

They have a long happy relationship.
2 kids 3 dogs and a few summer homes.

They get into one argument.

One stupid pointless argument.

Man drives. Cleans out a liquor store. Then just keeps driving..

Hits a car full of new drivers.

Everyone dies.

Months go by without him..

She couldn't live with the guilt of thinking she caused him to do it.

She's on her chair about to hang..

Remembers the letter..

It reads "If you die.. I woulda lived for nothing."

Years later she remarrys.
