A series of short and simple sentences with the same basic structure will quickly becomes repetitive and boring.
Example:
Spot was Jim's dog. Jim threw Spot the tennis ball. Spot caught the ball. Then Spot barked at Tom. Tom called to Jim. He wanted to cook the dog.
"I'm drunk and I don't care."
"I've been a drunken bastard since I was a child, and I don't care."

"I'm drunk and I don't care."
"I've been a drunken bastard since I was a child, and I don't care."
The rule, IIRC, is that you need a comma before a conjunction if the complete thoughts on either side are adequately long. There's wiggle room.
Where there is no wiggle room, is when Taylor is involved. He's too drunk to wiggle.
