Me: Hey, Professor Sna- I mean Severus.
Snape: Hi?
Me: I have a friend who has a dare for you.
usernamelikenoother : You should ask out Lily.
Snape: L-like on a date
usernamelikenoother : No, I want you to take her to the next Death Eater meeting. Of course I want you to ask her out on a date!
Snape: Why, do people keep talking about me and Death Eaters?
usernamelikenoother : No reason...

Lily: NO!!
Snape: What about me?
James: SHUT UP, SNIVILLUS!!
Snape: NO!! Would you want to, Lily?
Lily: Uh... sure Sev
