Having lived my whole life (up until recently, of course) in the same house near the freeway, I've always oddly found traffic noises comforting. Obviously, not rush-hour honking, just the constant rush I can hear in the distance when I have my bedroom windows open in the summer. Even the much more far distant sound of sirens in the middle of the night. I don't know why, I love those sounds.
Not unlike when I'm in the downtown of a city, I love that feeling of knowing there are thousands of people just buzzing about their day around me. It's part of the atmosphere, and I don't know why I just love it. It's probably due to the fact that I'd rather be with someone sitting silently, than be alone altogether. I have no idea why, it's just much more comforting.
Then, [just to contradict myself] if I were say, on top of a mountain anywhere in Colorado just taking it in, I wouldn't so much mind being alone...but I'm sure I'd probably still be a little bothered at the idea of something bad happening and being alone. Haha, but my irrational fears aside, I could enjoy beautiful nature alone and be okay with it. I will never be a country girl though.
I guess it's the comfort of knowing there are other people living life too, which sounds all too obvious, but I don't care. Sometimes the simplest things in life can blow your mind if you stop to think about it for a bit (with me, usually too long, lol).
