One day Ramon went to visit his friend Frank who was sick at home with a bad cold.“How are you feeling? ” asked Ramon.“Worse than yesterday, ” replied Frank.“I have a terrible cough, and there's not a drop of medicine in the house.”
“Cheer up, Frank.I'll send Blackie to the local drugstore for some cough syrup(糖浆).He'll be back in a minute, before you know it.” Ramon put a five-dollar bill in Blackie's mouth and the dog ran down the street.“And keep the change, ” Ramon shouted after him.
“Oh, Ramon, don't be silly.You know that dog won't be back with any medicine.” “Oh yes, he will, ” replied Ramon.Half an hour later, however, Blackie had not returned.Ramon was feeling embarrassed, and felt angry at his friend's little smile.
“Something has happened to him, I'm sure, ” said Ramon.“He obeys me as a rule.” Just then Frank saw Blackie at a distance.He hurried to open the door and let him in.Frank was shocked to see a bottle of medicine in the dog's mouth.
