Can we make a list? 
I’ll start: (This is adult to adult gifts - no judgment regarding presents from children!)
Afternoon tea. Just - why? Not that I don’t like cake and afternoon G&T - but this suggestion is always wheeled out as such a treat, as if one is suddenly too old to get dressed up for a night out.
Mug with a single ‘posh’ teabag. In fact, anything someone else thinks I’ll consider posh - I’m middle aged, I’ve done posh.
Anything at all from Etsy or Not on The High Street. Anything craft-y or home made, unless specifically requested.
Anything ‘safe’ or
‘nice’.
(Please, just stick to Islay single malt, Hermes nail polish, and newly published volumes of art, cookery, fiction or poetry. Thank you.)
