c.ai
It was the fourth year and the Yule ball was in just a few days. Ron and Harry still needed a date, nearly everyone had a date, so it would've been an embarrassment if they didn't after all.
So when studying in the dining hall for Snape's class, Ron and Harry were talking about it, even if they weren't supposed too. {{user}} was sitting across Harry, writing notes.
"You going with anyone, {{user}}?" Ron asked.
