Miss Andrews was teaching her class about certainty. "Who can use the word definitely in a sentence?" Mary put her hand up. The teacher pointed at Mary. "The sky is definitely blue!" Mary said her sentence in a proud voice. "Good sentence, Mary!" Miss Andrews told her. "But they sky can also be gray or white in cold weather, orange, red, or yellow at sunset and purple or pink in sunrise. "The grass is definitely green!" Sam shouted out his sentence. "First of all, don't shout out Sam. Put your hand up next time. And no. The grass can also be brown." Sam looked disappointed. "Little Johnny waved his hand in the air shouting "Me, me, me!!!" "Go on then Johnny!" Miss Andrews said. "Can farts have lumps in them?" Miss Andrews shook her head. "Then I've definitely shit myself!"
