Your leaving

My son is upset that his teacher is leaving and he asked me to write a poem for him ,which I have indeed done ,and as I appreciate the comments of all on here I would like to know what you think.I've writen it as though its coming from my son.I got inspiration from the kids as when the news of the teachers departure was annonced there were tears all round.

So sorry that your leaving ,
you will be very muched missed.
Your a top class teacher ,
made a difference to alot of kids.
You've made us laugh along the way ,
it still scares me when you shout.
I've learnt alot being in your class ,
its going to be different without you about.
It leaves me sad to say goodbye ,
so goodbye I'd rather not say.
Instead I wish you lots of luck ,
and all the best as you go on your way.
