Lucy, Megan, and open (3pm)
Lucy sat up at the first notes of the happy birthday song, using an oar to push her closer to the edge so she'd be able to greet her guests. "Megan!" She hadn't seen her old friend in some time - not since she'd first ventured back to the wizarding world, and that had only been briefly. It probably had something to do with the Quidditch season taking up all of Megan's time, but Lucy was glad to have time to reconnect.
"Oh, you didn't have to!" she said, throwing her arms out for balance as she tried to clamber out of the boat without getting more than her feet wet. She hadn't mentioned it was her birthday on the invitations, partly because she'd just forgotten and partly because she was inviting a lot of people she didn't know terribly well and didn't want to pressure them to bring gifts.
Safely restored to the poolside, she jogged over to Megan to give her a hug. "I haven't seen you in forever," she said. "How are you?"
