Do you ever think maybe your toddler just?

woke up on the wrong side of the bed? I swear mine did today. He has been crabby all day and not listening. He is crying over nothing and I just don't get it. He had a nap but he walks around crying and rubbing his eyes. He must not have slept good. He isn't sick either but everytime I tell him no he has a fit and throws himself on the ground or starts screaming hysterically.
