When you stayed up for 2 days straight watching the anthology.
When you actually lose some of your friends because they get annoyed of you talking about the Beatles all the time.
When you feel the urge to tell everyone in sight when a Beatles song comes on the radio that you know the song.
When you stay up all night watching their videos on youtube.
When you chose them as a topic in many of your english papers.
When you gets texts from your friends who don't even like the Beatles telling you that they're on t.v.
When you spend hours trying to learn their songs from a sheet music book you got from the library.
When seeing t-shirt after t-shirt of them in every single store irritates you because people they are becoming a "trend"
Yeah I would name more, but I can't think of any right now.
