Hi Andrew!
I didn't quite like the tone in the first para about your feelings towards the teacher. There is a difference between being informal and rude and I think you do tend a few times to ruder side.
Let me show you like...
I did not respect this man, Mr. Fleming, and I made sure he knew it.
aspects of life is Tom Fleming, a man I once so passionately hated.
The second one is good sort which does indulge a smile but the first one could me made better.
I was forced to spend with this man.
There is no need for "this man".... Is there?
There were so many other ways I wanted to spend the summer before my first year of middle school
I love this line. I can just imagine you, your feeling and this is a genuinely good line with a lame ending cause I think tennis does not make you embarrassed which would have been true if you were learning ballet(as a boy..)
On the whole, my aim is to show you there are few lines that need to be improved to give that punch and soul the essay. Your English is good- clean and simple without being childish. Just need tone the essay...
Hope this helps... :)
