One day, two friends Nancy and Jenny were sitting in a restaurant. Nancy asked Jenny about her age. First, Jenny tried to hide her age but when Nancy compelled her, she said, "I am just sixteen years old." At this Nancy said, "Last year you said that your age was sixteen and now again you are saying you are sixteen years old. What's this?" Jenny laughed and said, "I always stick to my words." Both the friends started laughing at this witty comment.
