It had been 7 years.
In that time she had gotten to know the postman quite well. They chatted almost daily as he went past her house on his rounds.
It always started with the shake of his head and then he’d watch her face fall.
He didn’t like to see her sad. He would give her the moon and the stars but he knew it wouldn’t be enough.
Everyday, he conjured the courage to ask her out and everyday he failed to say the words.
The stack of undelivered letters grew taller in the bottom drawer of his desk.

Or it could be that the letters were from someone else and he didn’t want her to have them…
I like the alternate endings!
