It will also depend on (assuming you are going to go to the courthouse and negotiate) whether you really can't afford the $155 and if that will affect your ability to survive, or if you want to keep the 155 so you can continue hanging out with friends and what not. No one "wants" to pay their ticket but saying you can't afford it and really seriously not being able to survive in your current conditions if you do have to pay it are in fact different things.
I'm not trying to sound like a richard, but they will look for that kind of thing.
