Sounds like someone expressing and thoughts and hopes that someone they like will confess mutual feelings for them on their day at the beach together. They might both be sleepy or hungover as suggested by heavy heavy (eye)lids. After a while it seems like the other person doesn't feel the same way and the narrator didn't have the courage to directly ask (a sunburn later im a coward and a fool) so they just make small talk. The narrator ends up reading trashy fictional novels.
