Interior design isn't really my thing.
If someone were to look around my room, much less my house, one would probably think they walked into an explosion of random hobbies and taste. If a Jack of All Trades had a room, it would probably be mine. In one corner sits a bass guitar with a skateboard hanging above it. On another wall sits a drum set, and on another wall, next to the bed, sits a computer desk desk with an old baseball glove hanging above it. The walls have flags, maps and portraits hanging from them, and there are three windows taking up the rest of the space. Honestly, there's no particular theme or consistency, and several of my friends have let me know that. (My office at work is worse, with glow stars hanging on the walls, making it the least professional office in the building)
It's interesting how sometimes (in my case especially) walls reflect bits and pieces of ourselves. It's been that way since we were kids. Where we once hung pictures of our favorite sports teams, favorite characters and favorite celebrities, we now hang bits and pieces of our new interests, whether it be photos of family and friends, works of art from hobbies or memorabilia from days long gone. Either way, our walls seem to talk and tell stories of who we are and what we're like.
If you could hear my walls talk, I'm sure they would have some interesting stories about the things hanging from them. The skateboard wall would probably say it has a skateboard hanging from it that was bought out of wanting to learn to skateboard to be 'cool' like the other kids. The wall with the map on it would probably say it has a map on it because of wanting to look 'well traveled.' I'm not sure what the wall with the flags would say, but probably something along the lines of wanting to feel like an All-American man, but not so much because of wanting to be patriotic. Forreal' though, my walls would probably be more honest with you about me than I would be about me. They've seen me at my lowest and highest points, and they reflect my aspirations and the 'who I want to be.'
My walls are probably a lot like your walls, because I bet your walls do the same thing. Of course, they reveal different things than my walls, but they definitely talk. When's the last time you stopped to listen/look at them? They may reveal something about yourself that you have never even realized.
