The many jobs done by headteachers

With regards to Martin Wynn’s letter (2 May), my father, also a headteacher of a primary school in the 1960s, used to see the children across a busy road after school when no lollipop lady was around. When he died, a mother came up to my mother at his funeral to say he had saved her son’s life. That is the only reward for such service.

• Why all this sniffy condemnation of people who aren’t engaging with art “properly” (Letters, 9 May)? If visitors choose to learn about an exhibition by listening to an audio guide, or by sharing a photograph, is it any different from buying the catalogue in the gift shop or sending a postcard?

• The storyline of The Archers has been very dreary lately. Can I suggest that if your readers would like some genuine countryside excitement, they should visit one of the many watermills and windmills which are open to the public this weekend as part of the National Mills Weekend.

• I grieve the rapid diminution of natural bluebells as the otherwise delightful ransoms (also known as wild garlic) spread at an alarming rate into their habitats. Is this happening throughout the UK or is it a southern England change?
