In an unusual moment of good sense, Ron had decided it would be weird to sit and watch the path for Lav's approach. Instead, he was facing the other way and counting the saplings. They'd need to do it anyway, and if he could come back with a number than he could pretend he'd been working if lunch did go a bit long. There wasn't really anyone who checked, as long as all the work got done before dark - and with the evenings getting longer, Ron could always stay behind after 5pm. There wasn't too much waiting for him at 'home' anyway.
He didn't notice Lav until she spoke. "Hi!" He scrambled to turn around and then carefully dropped the few feet to the floor. "You came." He didn't think about how the tiny phrase betrayed that he'd been worried she wouldn't, uncertain he was actually important enough to show up for. "Mum made lunch," he added, more cheerfully, gesturing to the picnic basket. He followed it with a frown. "I don't think my cooking's good enough to share." His soup certainly hadn't been, it had been horrible.
