Had to google "transience", lol. Sounds a little robotic, but with what haiku's limit you to, guess thats not too strange. It was still very sharp and to the point, needing to break ties with a friend, maybe one who has changed to the point where he/she is no longer him/herself... Happens all too often in life. Good haiku, awesome writing ^^

You know, you don't need to apologize for your work. =P

I liked these, all of them, but my favourite was the first. It had that air of complete, momentary clarity and revelation that haiku pulls off so well. Good work!
