Final answer:
The senator feels somewhat relieved because he and Laura share common sense, which provides a connection that eases the tension for him.
Step-by-step explanation:
The senator in question, presumably from the context provided, feels somewhat relieved when he discovers that he and Laura share common sense in their perspectives. This moment of shared understanding likely brings a sense of camaraderie or connection, easing the tension for the senator. The references provided contain multiple situations where characters find common ground or understanding, which seems to be a recurring theme in these narratives. For instance, the interaction between Louisa and Joe Dagget reveals a mutual acceptance of their situation and a hope for the other's happiness.
In the case of Mrs. Linde from the excerpt provided, there's a recognition of shared needs and a belief in a supportive partnership, suggesting a different kind of commonality and mutual reliance. The concept of finding commonality and relief in shared characteristics like common sense, resilience, and a sense of domesticity can be particularly poignant in literature and speaks to the human desire for connection and mutual understanding.
