Kate Barlow kissed Stanley Yelnats IV in the novel Holes by Louis Sachar.
This happens after Stanley is wrongly accused of stealing a pair of sneakers and is sent to Camp Green Lake, a juvenile detention camp where he is forced to dig holes all day. Kate Barlow, a legendary outlaw, was once a teacher at the camp and had a forbidden romance with Sam, a young man who worked at the camp. When their relationship was discovered, Sam was hanged, and Kate Barlow became a fugitive, taking revenge on the town by robbing the bank and becoming a bandit.
Years later, Stanley finds a treasure buried in the hole he's digging, a treasure that belonged to Kate Barlow. He eventually learns the truth about her past and her connection to Sam. In the end, Stanley and Kate Barlow share a brief but meaningful moment, where she gives him a kiss on the cheek, signifying a connection between the two.
This kiss is a powerful symbol of redemption and forgiveness. It shows that even though Kate Barlow was labeled as a villain, she still had compassion and humanity. It also highlights the importance of understanding the past and seeing people for who they truly are, rather than judging them based on their reputation.
