In my blog post of the 15th of June, 2011, I warned not to "slacken the reigns". This misprint may have been a simple typo due to my lack of attention or caused by my having watched a talk given by David Cameron to the House of Commons celebrating the 90th birthday of Prince Philip. Be it as it may, I should have written "slacken the reins". One of my followers kindly informed me of this and I immediately corrected it. Another follower pointed to the 'delivery' of a lot of rain in Cornwall these days.
To give the whole thing a phonetic twist: English is very rich in homophones. I grab the chance to draw your attention to this website with lots of homophones. It's maintained by Ian Miller. There's another one here.
