The generational point is bang on. A couple of weeks ago I had some older visitors to my garden and one came in the gate and said “What a lovely size garden you have! Mine’s six times the size of this and I just can’t keep on top of it!”
Did they really say six times 😂 not twice the size or five times? 6 is so specific (the others seem more generic exaggeration terms) and for some reason this has made me laugh mentally picturing them doing the actual maths in their head so that they could be sure to genuinely impress
