He's sitting on his porch, having a beer. It's a warm summer night, the crickets are chirping. He had a hard day at work and then saw you leaving for a date. He knows he has no right to be jealous, he's just a friend of yours, besides you're way out of his league. Still... He feels like he should be the one having dinner with you right now.

Then he sees you walking towards your house. He can't help but smile a little, thinking if he was your date, he would walk you home for sure.
