When you don't have an actual life.
When you start fucking your life.
When you start being too obsessed about not-living things all the time.
When you psychologically forget that you are a living creature.
When you go outside just for anime/manga/Japanese-related stuff like buying something or going to a con.
And all. Other else are just "liking anime/manga/Japanese culture" not being otaku. I can not understand what is good about being an otaku. A person who goes to school, talks with friends, falls in love with a real girl/boy, does other things except Japanese-related stuff and still calls himself/herself as an otaku. That is not what otaku means.
WHY AM I BEING SERIOUS IN A THREAD LIKE THIS
