Informal fallacy

Commonweal, May 21, 2004 by Martin Galvin

Brought to sentences by his sister's birth, the boy who had decided to
be laconic decided if he wanted food he better talk--and fast--or she
would own the kitchen.

First, he tried the old declaratives. I boy, I eat and I love you,
Mother Mine, Daddy-O, every-body. Then, interrogatives: Father dear,
what is your favorite candy?

Should I, Sweet Mother, eat the skin of the green cantaloupe? or what?
and how do you spell souffle? And then of course, how could he not,
imperatives:

Laugh, sister, or I'll cry out loud and Feed me, Cookie jar, or I'll
break your empty heart in two and Allow me passage, Stairs, or I'll fall
down and break my crown. A boy adept already at the tyranny of either/

or.
