Please do. We all make mistakes (especially when high) but if we aren’t willing to be corrected and learn... well you know.
Was it the fact that I began a sentence with “but” ?
This one is a matter of debate among academics. I try to avoid it, but sometimes it just feels right in “conversational” writing.
However, there’s no good excuse not to use “however.”
EDIT: Oh shit. Now I see the worse problem with that sentence. Why I couldn’t see it is a mystery to me...
