A toast to grannies and good manners

Sally Feldman’s article (Dismiss ‘grannies’ as frail old biddies at your peril: they’re some of the toughest activists out there, 20 August) reminded me of an incident a few years ago. I went to present a neighbour with a bottle of prosecco for their birthday. “Who is it?” someone inside shouted. “Just an old granny,” came the reply. I’m happy to be a granny, even an old granny, but not just an old granny. My young granddaughter was appalled and said: “Let’s go.” We did.Dianne Wood-RobinsonLeeds
Devi Sridhar tells us that any alcohol is bad for us (Opinion, 20 August). How times change! As an anaemic teenager in the 1960s, I was “prescribed” a small glass of Guinness to have with my evening meal. There was also a suggestion in the late 60s that it was good for new mums.Christine WaltersBuxton, Derbyshire
Zoe Williams makes me feel aged (What does it mean to be 16 today? It is totally different to when I was growing up, 19 August). We didn’t have a landline or a postcode when I was 16. In fact, we still had an outside netty across the yard, which was a nice quiet place to do a bit of revision.Jan DavinsonBeetham, Cumbria
Re the death of the interval (Is the theatre interval becoming a thing of the past?, 18 August), theatres make money out of interval bar sales and producers don’t want to interrupt the drama. But many punters won’t attend at all if they don’t get a loo break.Eleanor JardineBengeo, Hertfordshire
If Suella Braverman can trouser £60,000 for a few speeches (Report, 19 August), imagine how much she’ll get if anyone works out what she’s any good at.Ian Grieve Gordon Bennett, Llangollen canal
