Dockery and Son

Dockery and Son is a poem which explores the memories brought back by an old school friend, but with them, the unfocused attention set upon the passing of years and the value he has given his life. 
The poem explores the theme of Larkin with his obvious lack of offspring, but does the impression he gives about Dockery and his son, make it seem that Larkin wishes to have that life or is glad he does not To Larkin (or the persona) the perspective on children is seen as a "dilution" showing that it just makes us weaker- and carrying on into his philosophical shift of questioning the true meanings to where the "innate assumptions" for a child come from? Psychologically speaking, they're adapted through behavioral methods that we are brought up with, which could simply reflect upon a bad childhood experience Larkin had which has lead to this un-wanting attitude for offspring. 
    The epiphany Larkin has throughout his poem are of the facts that, life goes quickly, chances you make determine your life, and you can't go back on life choices, all of which point the the question of "what is it all for?" The unclear choices somewhat like "sand-clouds" to which are "thick and close" all point towards the "end of age", which in Dockery and Son represents death. Death of if you believe in heaven, hell or redemption, then your choices will have a purpose if not, then Larkin/ Persona is trying to contemplate the very reason to why you would have children, if it were to please you in the afterlife or the present life.
    The enjambment in the poem suggests a sense of continuity and flow. A life lived without significant hallmarks(wife,child), which resulted in the persona feeling empty with a hint of regret. The poem is a critical poem, Larkin does not find his lack of a son alarming-it simply leads him to the conclusion that life changing decisions emerge from mindless, thoughtless styles-"which something hidden from us chose".
