Having only recently learned that a tweet is a social media message, I read that “White House press secretary, Sarah Sanders, announced that Trump would be travelling to the southern border in a tweet” (Report, 8 January), which leaves me wondering if this useful neologism has also come to mean (a) a jiffy (b) a bullet-proof limo or (c) a fit of narcissistic presidential pique. Please help.

• Free TV licences for the over-75s are not forced on us (Letters, 5 January). The licensing office does not hold a licence-holder’s date of birth. If you want to keep paying, just don’t let them know you are approaching your 75th birthday. My husband (nearly 78) and I (76) still pay and are happy to continue doing so.

• It’s probably too late (now fashion is involved) to point out that the cap worn in Peaky Blinders is not a flat cap, but an “errand boy” or “baker’s boy” (Beckham’s menswear label doffs caps to Peaky Blinders, 7 January). The clue is in the name, as a flat cap is flat on top, not a pastry-cook’s puffed-up confection with a button in the middle.

• Please sack Marina Hyde! I’m getting older, and I almost had a coronary laughing at her latest salvo (No-deal Brexit is like Dragons’ Den, 5 January)!

• “Saudi women to get text when marriage ends” (Report, 7 January). That’s meant to be progress?
