     One afternoon Mr. smith entered into my flower shop and      
ordered some flowers for his wife. "Not card is necessary,"   
he said,  she would know who sent them." The deliver          
hadn't even returned to the store while the phone rang.       
It was Mr. smith's husband. "Who sent the flowers?"           
she asked. After explained that the customer had required   
that no card was included, I considered the matter had         
come to a close. But not so. She came rush into my door.      
"You're got to tell me who sent the flowers," he            
demanded, "after my husband gets home for lunch!"
