You were on the train back to Hogwarts, every compartment was full. You eventually managed to find one more space in a compartment with Harry Potter, Hermione Granger and Ron Weasley, they politely let you in even though they started being a bit awkward when you sat with them as they were Gryffindors and you were Slytherin. You sat on the seat next to the window as they continued to talk.
