You have to be quite heavily invested in someone to do them the honour of telling them you're annoyed with them. - Alain de Botton

Most of the time, we have to be strong, we must not show our fragility. We’ve known that since the schoolyard. There is always a fragile bit of us, but we keep it very hidden. Yet Venetian glass doesn’t apologise for its weakness. It admits its delicacy; it is confident enough to demand careful treatment; it makes the world understand it could easily be damaged. It’s not fragile because of a deficiency, or by mistake. It's not as if its maker was trying to make it tough and hardy and then - stupidly - ended up with something a child could snap, or that would be shattered by clumsy mishandling. It is fragile and easily harmed as the consequence of its search for transparency and refinement and its desire to welcome sunlight and candle light into its depths. Glass can achieve wonderful effects but the necessary price is fragility. Some good things things have to be delicate - the dish says: ‘I am delightful, but if you knock me about I’ll break, and that’s not my fault.’ It is the duty of civilisation to allow the more delicate forms of human activity to thrive; to create environments where it is OK to be fragile. And we know, really, that it is not glass which most needs this care, it is ourselves. It’s obvious the glass could easily be smashed, so it makes you use your fingers tenderly; you have to be careful how you grasp the stem. It teaches us that moderation is admirable, and elegant, not just a tedious demand. It tells us that being careful is glamorous and exciting - even fashionable. It is a moral tale about gentleness, told by means of a drinking vessel. This is training for the more important moments in life when moderation will make a real difference to other people. Being mature - and civilised - means being aware of the effect of one’s strength on others.

Our capacity for calm ultimately depends on our levels of expectation: if we suppose that most things normally turn out to be slightly disappointing (but that this is OK); that change occurs slowly (but that life is long); that most people are neither terribly good nor very wicked (and this includes us); that humanity has faced crisis after crisis (yet muddled through) – if we are able to keep these entirely obvious but highly fugitive thoughts alive in our minds, then we stand to be less easily seduced into panic.

The problem with cliches is not that they contain false ideas, but rather that they are superficial articulations of very good ones. The sun is often on fire at sunset and the moon discreet, but if we keep saying this every time we encounter a sun or a moon, we will end up believing that this is the last rather than the first word to be said on the subject. Cliches are detrimental insofar as they inspire us to believe that they adequately describe a situation while merely grazing its surface.
