Famous quotes containing the words mandatory and/or marks:
“Off south, the bison multiply so fast
a slaughter’s mandatory every spring
and every spring the creeks get fat
and Kicking Horse fills up.”

“[Children] do not yet lie to themselves and therefore have not entered upon that important tacit agreement which marks admission into the adult world, to wit, that I will respect your lies if you will agree to let mine alone. That unwritten contract is one of the clear dividing lines between the world of childhood and the world of adulthood.”
