"I hate him!"

"I hate her!"

"How dare he just dump me for Granger?"

"How dare she just dump me for Potter?"

Lavender Brown and Michael Corner looked at each other. They had both been ranting on their exes, Ron and Ginny Weasley. They had spoken out the last line simultaneously.

"We should," Lavender agreed eagerly. "Any ideas?"

"How about you go on a date with me?"

"Sounds like a plan to me."

And that's how Michael and Lavender started dating.
