I watched police vehicles rushing to Parsons Green underground station to try to protect us from people intent on pursuing their interests with bombs. And I remembered that only days ago, at the massive arms bazaar in London’s Docklands, that same police force had arrested around a hundred of those of us intent on nonviolently resisting the lucrative business of supplying people intent on pursuing their interests with bombs (Report, 11 September). Funny old world.
• As well as the abundant supply of EU flags on show at the Last Night of the Proms (Get real, Farage tells EU flag-waving prommers, 11 September), presumably it was also no coincidence that Nina Stemme sang of Poor Jenny who “in 27 languages couldn’t say no”. And, as if anyone had missed the point, “Farewell and adieu to you, fair Spanish ladies” was missing from Henry Wood’s Fantasia.
• I now know from the article on the fatberg (Monster fatberg found inside London sewer, 13 September) that 11 double-decker buses are the same weight as 19 African elephants. Please clarify re Indian elephants.

• By far the best, nicest and healthiest non-alcoholic drink is water kefir (Non-drinkers deserve a great adult cocktail, G2, 11 September). It can easily be combined with all sorts of flavours, and contains more probiotics than the most expensive tablets. I have never heard of it being served anywhere, but you can easily and cheaply make it yourself: just go online and look it up.
