I like that you tell just as much of the story that needs telling, and leave the rest unsaid,

One quibble: ‘Yeah’ should end in a comma and ‘grinned’ in a full stop.

oh, but that had so much potential to swing the other way! :P

This was just enough to be intriguing. I think a story could develop out of this.

No, I think there’s just enough…there doesn’t need to be any more of a story (although there certainly could be one, for sure).
