whats the theme of this story:
Kyle liked Lucy more than any other girl in the school, but he had an odd way of showing it. When she walked ahead of him in line, he kicked at her shoe. When she passed him on the schoolyard, he called her "Lucy the Loser." He even wrote a mean word on her homework during the bus ride to school. But what puzzled Lucy the most was receiving an invitation to Kyle's birthday party. Figuring that he was just planning a mean trick on her, Lucy decided not to go. As Kyle eagerly awaited Lucy's arrival, Lucy talked on the phone to Jacob. When Kyle finally realized that Lucy was not coming to his party, he was devastated.
