Frankly, I don't think I was particularly gentle. With some authors a certain method to get through is necessary - they have particular mistakes that are constantly repeated. Your mistakes are not often repeated and seem to be more a cause of attempting to get your assignments up in quickly.
Frankly, I have been very impressed with your skills and I look forward to being mean to you in the upper levels - I do suspect, however, that I won't get the same chance I usually get.
My glass is up to you and I look forward to having you chastise me for my writing.
