why I dislike IEP's

I went to my sons IEP the other day and I really didn't have to do anything or prepare for anything as nothing really has changed even though its his third year review time.. But in true form I seem to say the most fighting words even though I had nothing to fight or justify... well I felt foolish afterward but I guess that is my lot in life at times... putting my foot directly in my mouth... it gets old but still leaves me down on myself for saying the wrong thing at the wrong time...
