The grasshoppers may still be there, you just can’t hear them any more (Letters, 17 May). Grasshoppers and crickets “sing” at very high frequencies, and these can be lost as you age. A few years ago, while camping, my children complained about the crickets keeping them awake at night. “What crickets?” I asked. “I can’t hear any crickets!”

• Ironic that the government rails against home working (Remote working is making the UK a more equal place – however much Jacob Rees-Mogg may sneer, 15 May). As MPs have habitually gone home on Thursday evenings and only attend parliament for 30 weeks a year, perhaps they could set a better example.
