Archie and Ramona are very lucky. Their grandfather David lives with them. He's always ready to play games and read them stories.
For the last few days Grandpa David has been staying away from Archie and Ramona. He leaves the room when they're around. He says, "I'm busy," when they ask him to play.
Finally, Archie and Ramona's father, Leo, asks Grandpa, "Hey Dad, what's the problem? You usually love to play with the kids."
Grandpa David pulls out a small piece of paper from his pocket. It's a prescription for some pills that his doctor gave him. He gives it to his son and says, "Read this. That's why I can't play with the kids."
Leo looks at the prescription and reads it. "Take 2 pills a day. KEEP AWAY FROM CHILDREN."
