Lily not letting baby Harry eat a biscuit because it's his bed time.
James trying to sneak him a chocolate bourbon but Lily catches him and glares.
James picking up the phone and making a very discreet phonecall to an unknown person.
Lily looking out the window a few minutes later and seeing suspicious black dog carrying a packet of custard creams in his mouth, accompanied by a man that resembled a certain Werewolf she knows holding a leash and a packet of chocolate hob knobs.
Lily laughing to herself as she hears something go through the letterbox twice.
James rushing down the stairs and picking the items up and running back upstairs.
Lily looking outside a second time to see the man and 'dog' gone.
Lily hearing a strange noise before hearing voices.
Lily walking into Harry's room to find Harry, James, Sirius and Remus stuffing their faces.
The four of them all stopping still as she catches them and they expect her to shout.
Lily bursting into a fit of laughter as she picks the Digestive Biscuit out of James' hand and starts eating it.
All of them spending the night drinking tea and eating biscuits :3
