Jealousy?????

She attends a speech. She is seated next to one of her classmates with her arm behind him. She looks at this classmate as a little brother. She looks around the room and she notices him looking at her. He is not just looking at her he is looking at her with an intensity that takes her breath away. But she can’t act like she is looking at him. She looks around a few minutes later and he is still just staring at her. She starts chatting with her classmates. Later she looks around but he is gone.
