Mr. Black is very busy. He usually forgets date it is. Suddenly, he remembers it is his wife's birthday. He buys some flowers on his way home. When he gets home, he gives the flowers to Mrs. Black and says, “Happy birthday! January 15th is your birthday. I don't forget it.” “Yes, January 15th is my birthday, but it's January 16th today but thank you all the same,” says Mrs. Black with a smile.
