LightningScar: Hey, where's Ron?

SecretAdmirer: He isn't on Facebook anymore.

TheSmart1: What, why?

SecretAdmirer: Idk. He's on this new thing called 'Instaowl' and 'SnapeChat'.

LightningScar: What are those?

SecretAdmirer: They're new forms of social media.

TheSmart1: Why did he switch?

SecretAdmirer: Two reasons.

MommaWeasley: Ginny, I asked you to clean up your room!

SecretAdmirer: Mum, I will!

MommaWeasley: Do it now or I'll take away your phone!

MommaWeasley: Oh, and Harry, congratulations on winning another Quidditch match for Gryffindor. I'm sure if your parents were here they would be so proud of you!

LightningScar: Um...thanks, Mrs. Weasley. *weakly smile*

MommaWeasley: Hermione, congratulations also on getting that internship!

TheSmart1: Thank you, Mrs. Weasley. *weakly smile*

MommaWeasley: Now, Ginny, clean up your room!!!

[MommaWeasley has left the chat]

SecretAdmirer: That's why.

LightningScar: Yeah, no need to elaborate any further!

TheSmart1: Oh, Merlin...why did our parents have to get on Facebook!?! Why?!?

[DazzlenSparkle has joined the chat]

DazzlenSparkle: Respect your parents!

LightningScar: Is this the second reason?

SecretAdmirer: Yes.
