And this, ladies and gentlemen, is a life lesson right there.
I also had schoolmates who went through that phase, around 12, 13 y.o. - stopped talking about anime, deleted the anime songs from their mp3 players and engaged only in "popular culture" (bleh!).
And the way they would talk indicated they had "grown out" of anime, with phrases like "dude, you still watch that?" and "I don't listen to anime songs anymore."
A few years later, in high school, they message me saying "dude, you know where I can watch Bleach? The site I use is down!"
