I’m dreaming of finding a book I read in elementary school and lent out, but sadly never got back. Young adult, published before 1983 for sure. A boy from a small town was somehow lost, maybe on an island, and was alone for a while, unable to get home. Somehow he got back to his hometown, and on the day he arrived back, there was a town fair. He went up to the girl he had liked when he was younger who happened to be at a kissing booth at the fair, she didn’t recognize him, and he kissed her and said “you taste like strawberries”, and then she recognized him and was happy to see him again after so long.
