Unsettled

I received a call today from someone representing a motorcycle driver that she is representing from an accident I witnessed.  It happened almost 2 years ago.  I didn't see the whole thing happen but I knew it was going to happen and saw part of it.  I won't go into detail because the case hasn't been settled and I had to give a statement today for the 2nd time.  The funny thing is, the police never asked any of us standing around if we witnessed it and I was talking to the driver of the truck after it was all over and they asked for my name which is how I got myself into this in the first place.  The other side called me about a year ago and it was still easy to recall then but today I had a very hard time recalling whether or not I was driving or the passenger in my own truck.  David can't remember either.  I told the lady I must have been the passenger but really that was 2 years ago.  I remember the specifics about what kind of truck and his actions and the motorcycle but that's about it.  I remember we were driving home from somewhere and we also take the same route home so that part was easy but then she started asking what direction I was traveling and what direction my house faces and I got all flustered trying to figure it out because honestly I am terrible with directions.  Just ask my hubby and father-in-law who try to give me directions all the time.  Now I am sitting here wondering if I told it correctly or not.  They have been trying to settle with insurance for nearly 2 years.  It could go to court.  Are you kidding me?   I never thought I would have to remember this for so long.  I guess if you are a witness to something you should immediately write down the important information and keep it somewhere you will remember in case you get a call nearly 2 years later.  It is giving me such anxiety just thinking about it.  I'm sure I will forget about it eventually and the anxiety will go away but ever since the call I have been anxious.  I told both representatives that I didn't actually see it happen, I just saw the 2 vehicles.  I couldn't see either driver as it was happening so really I shouldn't even be considered a witness.  If they couldn't settle from my first statement then why are they asking again.  I had to say that to the best of my knowledge the information is true and I told her afterward that I really hope so.  I hope this whole thing disappears soon and that I don't get another call in another year.  Now I know why so many people don't stop or pull over when they see something happen.  They don't want to get caught up in this type of insurance battle and possibly court if that's what it takes.
