I enjoyed reading this. It is well written and does described loneliness and has given a voice to the feeling. The one thing I see is that if you remove the title, the reader has to decide what It is. Well done.

Your escalation is both logical and painful in its depiction. The true measure of a piece like this is that it vividly evokes bad memories of nights spent in teenage angst.

Strange that even though loneliness is silent it can speak more ... hurt more than any word could.
wonderfully written...

There's something so very appealing in this piece. Loneliness, and sounds, two words that pretty much contradict each others meanings.
Loved the simplicity, the descendant words; whisper, echo, screams, shouting. I really loved that :)
Well done!

Nice write indeed. And a great title!

I really like how even though it is short the storyline really feels finished and it was nicely developed. ^_^
