I don't like it when people start to get into the things that I like

Yeah basically the title. So someone I know recently posted something and starts liking things about my fave youtubers and musicians, and I feel devastated about it because how and when? And I feel like an as*hole for feeling this way because this is just plain immaturity.

​

But yeah, I am working on it already because even I, myself, hate feeling this way.
