Uncle Martin appears displeased with the idea of entertaining his sister Louisa's children, trying to suppress his frustration until he is away from her presence. He strongly believes that Louisa is mistaken if she thinks he will happily spend his time on her children. He expresses his unwillingness to engage in this task.
In response, Gervase challenges Martin's stance, insisting that he will indeed take care of the children right after breakfast, even jokingly suggesting they might have to tie him to the saddle. Gervase reminds Martin that Louisa has already indicated how important this indulgence is for the kids, emphasizing that he cannot back out of the commitment.
