Disregarding the fact that you used a comma after "me have doing" when you should have used a full stop, the way to have written the last few words would have been "do so in a way that is grammatically correct". The way you phrased it is, in fact, grammatically incorrect. Just saying.
Do you want to watch me disprove you in a matter of three steps? Because I happen to enjoy disproving people— it’s my hobby:
a) Since you seem to be so “well educated” in grammar and english, you should also understand the fact that each writer has their own interpretation and usage of commas. If you care to criticize me, then why not criticize e.e. cummings who disregarded a plethora of grammatical rules only to become one of the most highly regarded poets in history?
b) You actually lacked fluidity in your statement when you tried so explicitly to tell me where I went wrong. Maybe try rephrasing?
c) I’m not sure which grammar school you went to, but I’m pretty sure the majority of well educated human beings know that the period goes inside the quotation mark, not after, as you so mistakeningly placed it. Just saying.
Well said xD
