I can really relate to this. My brother and his friends come over to my house a lot because I still live at home. Whenever they are over they see my room with all my stuff in it and they are always like dude your a hoarder and you don't sell and get rid of stuff. All you do is buy more. I say well I am not a hoarder, I am a collector. I love to collect video games, movies, coins, and relics. Like the original poster said above, that is who i am. I keep my door shut at all times now and never let any of them in.
I used to have the xbox 360 in my room, but now i have to have it out in the living room so they can play it and not bother me with what I am doing. I of course get to take it back into my room when my bro's not home from college.
Another thing, they also rag on me that i choose to work and go to school instead of just go to a normal 4 year college. I tell them im saving money for other things and do not want to experience that drunk lifestyle like they are doing.
So man, all in all after my ranting. I totally get where your coming from.
