Thank you again, Professor Gower!

Thank you, Professor Gower! If I remove the "'s" after "how's the weather" and "rather hot, thank you", then add "phrases" after the word "you", would that be acceptable? Also, does an Incomplete still give me partial credit? My grade will no longer be an F if it does, which means I won't have to attend summer school, right?

Professor Gower, is "like most of my clients, instead of saying any of the expected "how's the weather over there"'s and "rather hot, thank you"'s, your curiosity gets the better of you and you decide to interrogate me" a grammatically correct sentence? I am sorry for being eight months late to office hours, but I need to get my grade above a 60%, so I hope you will alter your no extensions rule for me. Thanks for your time!
