I imagine myself to be a grown-up, as, presumably, do you. You think that because you negotiated puberty and developed secondary sexual characteristics, and got qualifications and opened a bank account and subjected yourself to the scrutiny of anti-terrorism laws and anti-money-laundering laws and learned to drive and got a job and perhaps a spouse and maybe children, and quite possibly even pay your taxes, you are a grown-up.

Sometimes, things strike you as a bit odd. It strikes you, for example, as out of kilter that between getting off the plane and reaching the outside world at London Heathrow there were, at last count, 93 notices telling you off for things you hadn’t done or which it hadn’t even occurred to you to do.

The plain fact is that you are being treated like a baby. You, I, all of us are on the receiving end of a sustained campaign to infantilise us: our tastes, our responses, our behaviour, our private thoughts, our decisions, our buying habits, our philosophies, our political sensibilities.

We’re all big babies at the Telegraph. The authors list at the bottom of how to be an adult is worth linking to alone. Example:

Don’t be affronted Being affronted (or offended, or complaining about ‘inappropriateness’) is no response for a grown-up. Only children believe the world should conform to their own view of it: a sort of magical thinking that can only lead to warfare, terrorism, unmanageable short-term debt and the Blair/Bush alliance
