Your school had booked your year level a trip to London. On a plane with other people since they weren't too rich.

So, as expected, when you arrived, some old lady was sitting in your seat. She said

"Oh dear I'm so tired, I can't get up. Please go sit in my seat. Be my guest."

So you walked down from first class straight to economy then to business. The ladies seat was next to a tall dude with his headphones in. He had his stuff on your chair and he was vibing to some music, bobbing his head and singing something

"Lalala-!"
