So much for knowing someone

Just a warning this is an unhappy me about events transpiring, so sorry.
Have you ever made friends with someone and figured after a while, yeh I kinda get him/her only to be wrong? Don't you just hate it? I'll admit I hate being wrong about people, because usually I like to give them the benefit of the doubt and try to see the best in them for a while. With my friends even more so I chose to be friends with them for a reason and once that reason dies I hate to let go but they do. Why do people who you know were perfectly good, who you love to be around and made awesome memories with change into someone you'd never associate with? Why do they do it? One day your happy the next they meet someone or see something and the do a 180, turn right round away form who they were and become something who they aren't? And what's worse is when they don't even notice what's happening, when they think everything's the same, that noting is changing in the friendship and meanwhile their losing the spark in their eyes, and the realness of their smile becomes a dim memory, the once easy conversation you had turns to a dry river and all is dark. Your mind can't take it anymore and yet still you hold on to a ghost of a memory trying to call it back to who and what it was as the stone round its feet drags it deeper. Yes I feel dark tonight and that is why I can't sleep even as the sun is set and my body is drained my mind forces me to let out the strange un bearable anguish as I watch this train wreck happen in front of my eyes but what can one little girl do against a 2 ton hunk of speeding metal? Nothing.
