What got me wondering was reading Carol Shields' book Unless, in which a young woman suddenly abandons university to live on the street with a sign saying "Goodness". Her parents are baffled as to why she's taken this path, and her mother in particular wonders whether something in her upbringing has caused it.
Of course the daughter's strange behaviour could be caused by any number of things other than her upbringing, but naturally her parents start pondering their own possible influence in what's happening.
I also wonder if women in general are more likely than men to assume a personal blunder when a child goes off the rails (or just does something disappointing).
I get the impression (nothing was ever made explicit) that my parents were disappointed by my choices in life and felt I could have "made more" of myself. They maybe expected me to be a high-flying journalist or a best-selling novelist. In which case, did they blame themselves for not making me ambitious enough? Who knows?
It must be tempting for parents to criticise themselves for all sorts of perceived failings in their child, even if there's no obvious cause, and even if the supposed failing is not seen as such by anyone else.
It must also be tempting to have grand ambitions for your child that are simply unrealistic, and will inevitably lead to parental disappointment. Let's face it, you're more likely to be raising a tone-deaf karaoke fan than a budding Beethoven.
