"Harry, why were you and Sirius using my pensieve to watch his wierd memories of werewolves?"
"Sir, we were watching Pettigrew get assaulted by one."
"Ah yes, I remember that interesting night. Invite me next time, 100 points to Gryffindor."
Harry, I heard Malfoid gave you her first kiss. Reminds me of the time when we were being chased by a werewolf. She caught Pettigrew and you could hear his screams from the Shrieking Shack. Your father and I could not stop laughing. Is there a pensieve nearby? I need to show you.
