Johnson's malady is difficult to diagnose

We can’t be the only subscribers dependent on newspaper deliveries. Rural village, no shop, no public transport. Yet every day our newsagent, Trevor, or his sister Glenda, deliver the Guardian. Some acknowledgement is overdue. Our thanks to all those who deliver the papers, in all weathers, during this lockdown.

• So since his illness Boris Johnson may be lethargic and with a reduced capacity for sustained work (Letters, 29 May). How can they tell?

• You report that one of Boris Johnson’s alma maters is to close (Coronavirus closes prep school attended by Boris Johnson, 1 June), and that the school trust’s CEO said that Ashdown’s impact will be felt for generations to come. Well, quite, but almost certainly not in a good way.

• I feel Rhiannon Lucy Cosslett (Lockdown has taught Britons the joys of the outdoors, 1 June) hasn’t visited north Lancashire in February, or even during an average summer. We’ve always known how to enjoy the outdoors up here but it usually requires walking boots, a cagoule, waterproof overtrousers and the ability to keep moving.

• A number of your readers have reported hearing the cuckoo (Letters, 21 May). My wife and I were quite excited to heat the cuckoo for the first time in our part of Hampshire for many years. This particular cuckoo seemed to follow at a distance on walk from Langstone towards Emsworth, and called many times.
