Lily Evans was wearing mismatched, knee-high socks.
In the dullness of History Magic, this fact had James Potter staring, fascinated, at her feet. Her left sock was scarlet; her right sock was gold. She seemed to sense his eyes on her, and so she looked up, their eyes meeting.
He gestured to her socks. She laughed.
"Couldn't find a matching pair," she whispered with a wink. "My story is that it's for House pride."
At lunch later that day, everyone watched as all the Gryffindor girls entered the Great Hall wearing mismatched socks. No one noticed Lily Evans laugh and kiss James Potter on the cheek.
