YSK it's either "should have" or "should've". "Should of" is incorrect
Why YSK?
The first person who typed "should of" probably heard of it in real life that was meant to be "should've", they typed "should of" online and readers thought that it's grammatically correct to say "should of" which is in fact wrong and it became widespread throughout the years on Reddit.
I know right, I know people make careless grammatical mistakes all the time, including me, which is completely fine but people outright thought that "should of" is correct and use it all the time starts to get annoying
Oh, Dude! I'm 99% for it. On the night before my uncle's funeral, while labeling photos for the slideshow, two of my cousins got into an Oxford comma fight.
John, Joe, and Jeff.
Take out the second comma.
But it's right!
But it looks stupid!
Fight! Fight! Fight!
Ah funerals, people really get upset over the smallest things due to all the pain from the loss. I don't want to ever go through that again but I know it's just a part of life. :(
Damn man, I'm really sorry for your losses. I've experienced something similar in the past. It's like when one person dies, more follow shortly. I feel like when people loose their loved ones, its like some peoples bodies when they are old just give up as the person they loved disappeared.
It's mandatory in a series, only. Something is only a series of there are three. Plenty of time the cadence and diction sounds like a series but isn't.
If the first two or last two are antecedent to one another, you don't need the comma. Said another way, if the first or last noun is not severed from the second, you need a serial command to indicate that.
