Use a comma before coordination conjunctions that join independent clauses. (Oh man, that’s a mouthful)
See, I got this here sentence — Snake owes me 10 large.
And I got another one ———- I’m on my way to punch out his lights.
Them two are complete sentences, subject and predica— verb thing.
So when I puts ‘em together, I needs a comma, like in:
Snake owes me 10 large, and I’m on my way to punch out his lights.
The rule works for:
I drove up to Snakes, comma, but he was waiting for me, comma, for he is a shifty character, comma, nor is he dumb, comma, or maybe it’s me, comma, so I got out of the car, comma, yet I forgot to get my piece out of the trunk, comma, so I was shot for murdering the English language.
