Al entered the area in time to see his parents hugging and couldn't help the grin that flickered across his face at the sight. Granted his mother was much younger than he was used to her being, and she looked a little strange hugging a man clearly older than her in such a manner, but out of all of their children, Al was the least phased by those facts. He was just glad they were finally spending some time together.
Clearing his throat slightly, his smile turning a bit embarrassed as he realized he'd been standing there for a few seconds longer than what would be proper, he couldn't help but state in a teasing tone, "Just wait'll James finds out you two were practically snogging in a Muggle park without a single care as to whose around. You two will never live it down."
