The speaker is saying that is wrong and deceives the friend's own self if he decides to remain single and childless. Line 11 also contains a sexually suggestive play on words when the speaker says "having traffic with thyself alone". The idea of being alone is used by the speaker as being the pathetic alternative to marrying and having a family. The speaker seems to personify nature in the first quatrain in saying: "Nature's bequest gives nothing, but doth lend, / And being frank, she lends to those are free" (lines 3–4). The speaker is saying that nature gives gifts at birth, and calls on people, giving something inhuman human-like characteristics. Several words in the sonnet; such as "bequest", "usurer" and "sum"; also make explicit the accounting motif of the prior sonnets. The couplet sums up with a potential answer to all of the questions that the author was posing throughout the entire sonnet. He says, "thy unused beauty must be tombed with thee" in the first line of the couplet. This is suggesting that the young man has valuable attraction that is not being used properly or appreciated. It seems as if the speaker is insinuating that the beauty will die with the young man. The last line of the couplet says, "which usèd, lives th'executor to be." Here it seems as if the speaker is saying that if the young man uses his beauty, then it will prolong his life. The word "executor" hints at both death and accounting. Criticism Many critics seem to agree with H.E. Rollins that Shakespeare's Sonnets "provide direct evidence concerning Shakespeare's private life". There was even a scholar who posed the idea that the sonnets are divided into "two groups: all those which suggest moral irregularities are 'dramatic'; the rest are written in Shakespeare's own person". "Use" One of the major themes throughout Quatrain 2 of Sonnet 4, as well as in a few other Procreation Sonnets, is the variations of "use", as noticed by Halpern. Krieger points out that this repetition of the various forms of "use" are also seen in Sonnets 6 and 9. Critics take the repetition of different forms of "use" to mean many different things. It is pointed out by one critic that "the procreation sonnets display with particular brilliance Shakespeare's ability to manipulate words which in his language belonged both to the economic and the sexual/biological semantic
