I haven't won. (Yet?!)
But I do kind of love reading fascinatedly about the lottery curse, how big winners tend to fall out with their spouses and friends and family. My DH says we could prevent all that by telling nobody. I then asked if that included our parents, who help us out financially in a modest way sometimes, as we ought to tell them we wouldn't need that any more. Dh said we'd tell just parents. But MIL, who is lovely and I love her, is the town crier and would tell her whole village within minutes without thinking.
I've got a ticket for tonight's draw and I find myself idly worrying about this as if I've won the 15 million pounds already or however much it is.
