Everything I Needed to Know (G; Snarry; 100 words)
"Everything I needed to know, I learnt from this book," Harry told his daughter, watching Eileen's lower lip stop trembling as she reached for the text.
"Really. It was your father's, you know, so it should bring you luck in his class."
"Thank you, Daddy!"
When Eileen had left, Severus, who only taught advanced students now, entered the room to glower at Harry.
"She was worried. She doesn't have to know that your actual book burnt—"
Severus pulled Harry up, kissing him quiet.
"Mmm, that's better than a lecture, Professor."
"Idiot. I've already given Eileen 'my old book'."
