Inservice

I think that teacher inservice days are a waste of my time. Why is it beneficial for me to go to a class all day long that is supposed to teach me all of these amazing new things when what they are teaching is what I JUST learned in college not even 2 years ago. I mean really... are there teachers out there that have no clue what they're doing?? Becuase that's what I feel like this class is for. Also, why oh why do teachers complain SO much about their students? If you have so many negative things to say why are you a teacher at all? Deal with the fact that they are kids still and have problems and have drama and have a hard time with life sometimes and they are HUMAN so they aren't going to be perfect all the time! Blah... I need a the weekend.
