>>5007923when i was a kid i always thought that "goodbye"was something you said to someone whom you were never going to see again because it was always translated into bulgarian as "sbogom" (go with god). which is something you say to somebody you're never going to see again.
but later on some american told me that you can just say goodbye whenever you want and it was interchangeable with "bye" and i was wrong. made me feel dumb desu
