Mark it wrong

Teacher - If one flower has 3 petals, how many petals are on two flowers?
Little boy - Sixteen
Teacher looks at the boy's picture - Oh, I see. You put 8 petals on each flower. The problem says that there should be only 3.
Little boy - Three petals is a sad looking looking flower. I think there should be eight. I like big flowers.
Teacher - You can't get the right answer if you don't draw the right number of petals.
Little boy - Ok, mark it wrong. I won't draw dead flowers.
