After an especially "busy" day, a preschool-age boy overhears his mother say, "He's been a monster all day." So the little boy starts to fantasize about what life as a monster would be like. "I wonder why Mommy thinks that of me? / I guess if she does then a monster I'll be / I'm big and strong / I grumble and growl / and scare people off / with a sneer and a scowl. / Being a monster is fun " There are no rules to remember or manners to follow. And monsters can stay out as late as they please, scaring everyone away. As it turns out, being a monster isn't all it's cracked up to be. No one wants to be friends with a monster. And who will read a story and tuck a monster into bed? Maybe being a little boy isn't such a bad thing after all.
