I am not talking about mixing tenses in the same sentence, which is the only real information I've found, but mixing within a single paragraph.
In the essay I am writing about my past experience playing on a team, and in one of the paragraphs, the form is like this:
1) a general situation that occured nearly every game (an introduction of sorts).
2) an in-the-moment description in present tense of the real action.
3) pulling away from the real time, back describing the end of what normally happened.
My professor indicated that this was a confusing use of tense, that at least there should be paragraphs separating the tenses or just put it all in the past tense.
I used present tense for the very specific reason of highlighting the difference between a seemingly repetitive past with the actual emotion of the moment, so I do not want to flatten it all into the past.
How I am I supposed to mix tenses properly?
