First of all, the word addiction is a bit uncomfortable. Addiction still makes people feel a little heavy. In my impression, the word addiction is mostly a derogatory term. The subject mentioned in his description that his good friend is a local tyrant. Then this room is too expensive for the subject, but it is nothing in his friend's consciousness and has not affected his daily life. Then this can only be regarded as a hobby at most. What qualifications does an outsider like the subject have to make irresponsible remarks about his behavior?

If the subject can't accept it, let me give another example. What do you think of the women around you who are addicted to buying clothes? Maybe at this time, the subject will feel that there is nothing wrong with it. Girls like it, and they get satisfaction from it. In the same way, the local friends of the subject are only satisfied with enough handwriting to buy their favorite characters. It's just that the two groups have different ways to get satisfaction.

I think the subject thinks that the periphery of animation is conceptually useless. So its value will be misjudged. Just calculated its practical value. Plus, it's not the same level as the local roommate in your class. These two reasons have finally caused the reason why you are asking this question now.

To sum up, don't point fingers at other people's hobbies just because you don't understand.
