3:2 "when my love swears she is made of truth"

Shakespeare's sonnet, "When my love swears she is made of truth," changes meaning with each time it is read. Originally, this sonnet seems to describe a couple so in love that they forget their flaws when they're together. When read again, the ambiguous words stand out, such as "told" and "lies." The reader then notices that the speaker of the poem and his lover are of different ages, the latter being younger. The speaker seems to appreciate his lover's attempts to flatter him. However, "And wherefore say not I that I am old?" implies that the lover doesn't know the man's age. The line before that, "But wherefore says she not she is unjust?" suggests that the woman does not say whether or not she is faithful. "Oh, love's best habit is in seeming trust." This "seeming trust" is important, as it argues that the lovers feel that they trust each other, but still know it's not all real. From these lines, it can be seen that the relationship is not necessarily based on lies, but rather a small amount of truth. For the speaker, this doesn't seem to be much of a problem, as "lies" changes meaning in the penultimate line of the sonnet. "Therefore I lie with her and she with me," could suggest the two tell each other lies, flattering each other. However, it can be assumed that "lies" is referring to lying in bed together. This act clears the minds of the two lovers, making them forget their flaws and be consumed with the other. 

Shakespeare's sonnet briefly tells the story of two lovers, who are presumably insecure, as they trust each other, even while knowing the truth is not always told. Age and faithfulness are not shared at all, so are not actually lied about. This relationship is based on the desire to be wanted.
