If I won a very large amount, or even a moderately large amount, I wouldn't tell anyone.
I would carry on as before while the money sits in the bank gaining interest for a while. I would set up trust funds for the children in my life, not tell them, but let it drip feed them smaller amounts every now and again as 'gifts' so they don't get used to it. It will be there when they really need it and know what to do with it.
I would do likewise for some charities so they get a regular contribution indefinately but no one off lump sum.
Then I would work out who really matters to me and slowly fade away from the rest of the social group so that no one missed me, or at least not for long.
I could then use the money to do some good without unwanted 'friends' and neighbours giving me grief for not sharing it with them.
So if I gradually stop posting....
