State how serious the matter they were fighting about was

Now this in itself was most extraordinary. They were
bickering and shouting about some obscure matter. As I
recall, it had something to do with an event some twentyfive years previously and they had different ideas as to how
the event had turned out or where it had occurred, and the
discussion got hotter and hotter. At first I was amused, and
then I was alarmed. My father said, “That’s the way you are,
always so sure of yourself.”
“I ought to know. I was there.”
“I was there, too.”
“Well, you don’t remember then.”
“My memory is perfect,” my father shouted.
My mother said, “Don’t shout at me.”
“I’ll shout at who I please.”
“Not at me, you won’t shout.”
It went on like this with me standing there holding
the scallops in my hand and wondering. They kept at it like
newlyweds for about fifteen minutes. Finally my father got
real angry and took his hat off the bed he sat beside and
rushed out of the apartment slamming the door.
“Let him go,” my mother said.
“I guess I’ll have to. What were you fighting about?”
My mother shrugged. “I don’t remember. He’s just so
stubborn. I keep hoping he’ll outgrow it.”
“If he hasn’t now he never will.”
“Well, he better. I won’t put up with it much longer.”
I sat around for a while, and then I put the scallops in
the icebox. I was beginning to smell like Gloucester, Mass. I
told my mother not to worry. She said, “Humph!” I left.
