Style of "Popular Mechanics"

This short story was written in what seemed like a rather informal style. The most obvious informality was that it lacked quotation marks around the husband and wife's statements. There was also a common pattern present. Each line switched between the husband and the wife yelling at each other and arguing.

"I want the baby, he said.

Are you crazy?

No, but I want the baby. I'll get someone to come by for his things.

You're not touching the baby, she said," (344, handout).

This back and forth arguing coincided with the couple's "tug of war". Their yelling back and forth was similar to their tugging back and forth of the baby in the end.
