"This park has always been my favourite place," said Ben as he walked with Hannah. "I remember when I was a kid I used to spend hours here. Building forts, making friends, going on secret adventures..." A slight smile crept across his face, a wistful look in his eye.

Hannah smiled back. "Sounds like fun. It’s got a lovely feel to it."

They reached the old oak tree where he remembered carving his initials with his childhood crush. He paused, a strange feeling creeping over him.

Hannah pulled out her phone. "Oh, I have to go to the grocery store. Sorry, I forgot. I just got a message from Tom."

Ben frowned. "Tom? Who's Tom?"

Hannah turned, looking surprised. "Oh, he's the guy I was with before." She paused, then grinned. "He loves this place, too."
