A lively online debate was triggered by The Guardian piece Just one little tattoo in which a pseudonymous mother describes the horror of discovering her 21-year-old son has a tattoo.
It would be fair to say she flipped out over it. When she could finally bring herself to talk to him, she said: "All those years of [my] looking after your body - taking you to the dentist and making you drink milk and worrying about green leafy vegetables and sunscreen and cancer from mobile phones. And then you let some stranger inject ink under your skin."
Her emotional and dramatic piece of writing was dubbed an overreaction by the majority of people who left comments - many of them vitriolic and critical of her relationship with and possessiveness of her adult son. The piece was described as "mawkishly self-obsessive" and "bats**t mental". But there were also those who consider tattoos to be "ugly desecrations resonant of self-loathing, aggression and crudity" akin to "having a Banksy mural put on the White Cliffs of Dover".
Tattoos may mark significant occasions such as births, marriages or the death of a loved one. Sometimes, of course, there is cultural significance attached to tattoos but often they're chosen simply for their decorative qualities. It seems they can be addictive too, with un-tattooed flesh being viewed as a blank canvas for more ink-work.
David Beckham's tattoos represent his children, special dates and the number on his football shirt while Angelina Jolie is said to have a total of 13 meaningful tattoos.
