Hey guys. I was just re-reading Chamber of Secrets again, and I think I found a small flaw. After Harry and Ron flew the car to Hogwarts, they both got detention. Harry had to serve his with Lockhart. He was writing the addresses on Lockhart's envelopes so he can answer his fan mail. But why would they need envelopes. In the Wizarding World, can't you just tell your owl who you want the letter to go to? I'm not sure if this is the case... tell me what you think!
