I am too fond...more cunning to be strange (102-5)
I am too fond;
And therefore thou mayst think my 'haviour light:
But trust me, gentleman, I'll prove more true
Than those that have more cunning to be strange.
Juliet is concerned that her private thoughts (overheard by Romeo) make her seem too eager - too quickly won (95). Thus she assures Romeo that, although he may believe her to be sluttish (thinking her 'haviour light), she will prove more faithful (true) than other women who appear chaste.
