Sarah spotted the crumpled paper peeking out from under Leo's pillow. A thrill, like the first drop of a roller coaster, zapped through her. It was his bucket list! "Climb Mount Kilimanjaro," she read aloud, a smirk tugging at her lips. He'd never mentioned *that*.

She flipped the page, her fingers eager to turn. "Learn to speak fluent Italian." Ha! She scribbled a new entry beneath it: "…and use it to order a pizza, only."

She pictured his face when he discovered her edits. She added a few more ridiculous items, including "Become a professional competitive hot dog eater." The feeling in her gut was purely anticipation. She carefully tucked the altered list back where she found it, a giggle escaping as she did.
