And although Kerri was not feeling well, she did her best to hide it so she could enjoy David's visit. And David had a big box, a surprise for Kerri!
You would never know it by her expression, but she really is thrilled with her new Harry Potter poster-board.
And after playing Hangman and Tic Tac Toe with David, they used the box the poster came in to create a clubhouse. Because the box is always the best part.
Thank you cousin David for brightening Kerri's day, you made her feel a whole lot better - and not just because of Harry!
Life with Kerri is pretty dramatic.
