Private and pay for the best financial adviser and Publicist I can find to keep my situation under wraps.
Work would just never hear from me again, I'd courier back my laptop and work pass, then move home and change my email address.
Don't have much in the way of family and friends but the ones I do have would be set for life.
Would deregister DD from school for a year while me, DH and DD travel the world and find our new home.
Not bothered about cars, but I would like one that's hassle free so I'd lease a brand new, reliable runaround and swap it out every couple of years so I never have to do maintenance or MOTs.
Home would be something with a couple of reception rooms, a dining room, utility and 4 bedrooms. That would mean DH can have a man cave, I can have a sewing room and we could have a library/playroom downstairs.
Then we would work out the best way to benefit the charities we support, and invest enough so that we never have to worry about money in our old age and DD will have a fund for education, house, setting up her family whatever that ends up looking like.
