I am kind of on your side a bit @Loudnproud
DH and I have a cottage in a highly sought after village in the shires, near woodlands, the canal, and the river, and 2 miles from the nearest A road. No-one comes here unless they're visiting someone (or they live here!) Basically, it's not a through road to anywhere, except to 4 or 5 fairly large farms. It's crime free and so quiet and peaceful.
We both work part time - me 20-ish hours a week, him 26. We have a 3 year old car.
This year we had a week in Portugal. Also a 3 days trip to London, and a few day trips, and a few meals out (just carveries.)
Several times, my DH has had people at his workplace fishing for information, wondering how we manage to afford this nice cottage, a new-ish car, and holidays abroad, whilst both 'only' working part time. DH says (funnily enough) 'we had a bit of a lottery win a little while back!' He doesn't care, but it annoys me. I think 'what bloody business is it of theirs?!' 
A couple of women at his workplace have been going on about how they're struggling with the bills and the mortgage, strongly hinting at him giving them some money. One said 'you could help Mr lottery winner man.' DH said 'not a chance, my missus is in control of the finances.' Cheeky cow. 😆
As has been said, just say 'yeah we won on the Euro-millions recently.' If they ask for any money, just say 'oooh, sorry my husband is in charge of the finances, I couldn't possibly dish any out.' Or 'no sorry, this money is for our future...' Because someone will hint at having some money off you. Some people are shameless cheeky fuckers! 😆
