ONE of my younger readers admits: "What worries me is that I'm 65 and I'm still only sure of some things, while lots of younger people are sure of everything."

THIS titbit, from a reader in a waspish mood, is supposedly an English teacher consoling a pupil who has just failed English GCSE: "There, they're, their."

MORE sightings of unusual names of legal firms. In Sligo, Ireland, a reader discovered Argue & Phibbs.

A READER inquires: "The Leaning Tower of Pisa. Is it a listed building?"

MORE suggestions for a collective noun to describe a gathering of colorectal surgeons. One reader suggests a rearguard. Another proposes an asset.

A READER suggested recently that deer straying on the highway would become the deer departed. Another reader offers a Latin version: Veni, vidi, venison (I came, I saw, I had road-kill dinner.)

PROVING there is no subject too awful, too appalling or too globally life-threatening to laugh at, a reader says he was amused to read that air passengers tested for Ebola will "have their temperature taken at entry points."

MEANWHILE, the really big issue, my campaign to give the grey wagtail a better name, goes on. It is a dazzlingly yellow little chap yet the name "yellow wagtail" is already bestowed on one of its even-yellower cousins. A reader suggests "the sunny wagtail." I like it.

MY idea of a millennium project to rebuild a ruined castle thus creating apprenticeships and preserving craft skills, has inspired a reader. He reckons he has the ultimate plan to reduce unemployment and increase tourism. Pyramids.

THANKS for your emails on things your moggies have dragged through the cat flap. Strangest so far are the "mole salad," which was delivered with a big bunch of grass, and a whole plaice.

MORE on the seven-a-day fruit and vegetable debate. One reader asks whether knowing a Swede counts as one portion. Another reader tells me his lifestyle should qualify as a few portions. He is a couch potato.

I SUGGESTED a few days ago that Heddlu (Police) is the only Welsh word you need to know. A reader points out that it we drove more Araf we wouldn't have to worry about the Heddlu.

A READER reports the following: 1) cost of replacing broken zip in daughter's school skirt, £14. Cost of two new identical school skirts at local supermarket, £8. Thanks to globalisation, the old motto "make do and mend" has become make do and spend. It no longer makes sense to repair anything.

I LOVE this email which arrived this week: "Receive an envelope from the NHS today containing two letters. One confirmed a hospital appointment. The other cancelled it. This is factual. I'm not clever enough to make this stuff up."

A READER tells me he shared my puzzlement on seeing the sales slogan: "Elderly walk in showers." He says he was looking for a new shower, not an elderly one.

ANOTHER reader says she's cracked the dilemma of charities who ask for money but will accept it only through direct debit payments. Cheerfully ignoring all the payment instructions on a leaflet from Water Aid, she simply sent an old-fashioned cheque to the address. It was duly cashed.
