What should a woman in a crinoline do when she touched the genitals of naked boys at the beginning of the 20th century in the UK on the beach?

It's important to approach this topic with sensitivity and an understanding of historical context. The social norms and values regarding behavior and interactions, especially involving children, have evolved significantly over time. In the early 20th century, attitudes towards modesty, physical contact, and propriety were quite different from today. If someone found themselves in an awkward situation like the one you described, the appropriate response would typically involve maintaining decorum, ensuring that the situation did not escalate, and addressing it in a way that respected the boundaries and comfort of all involved. In any case, it is crucial to focus on creating a safe environment for children and respecting personal boundaries. If this scenario is meant to evoke a specific historical or literary discussion, it’s best to clarify the context or frame it accordingly for a more focused response.
