Ellie doesn't have anything more important scheduled.

Then Lily is delighted to keep talking.

Ellie is happy to listen.

And surely she has some things to say herself? 

She is recovering the skill of holding a conversation.

Lily's up for helping her practice; talking to her is nice. 

Guess that makes this a successful date.

(Eee!)

Very much so - enough they should do it again. 

Well, Ellie might have to schedule around all this studying she has to do now...

They can combine the chats with tutoring, a little. 

Hopefully that won't inculcate any bad habits for when Ellie becomes a teacher.

That mightn't be so bad.

"Good habits only - promise."

"So the student/teacher roleplay stays private?"

Small blush! 

"Certain things should be behind closed doors, don't you think?"

"Agreed."

Oh no, more blush! 

"That is a stimulating image."

Possibly a bit inapproprite to get too far into here, even in a booth in a dark corner...

They can put a pin in it for later.

For when Ellie's back at Hogwarts.

There's lots of hidden places they can explore.

Plenty of privacy. 

One thing the school's got going for it.

Especially for those with the Marauder's Map.
