Windfall

I read in this morning's paper that a young lady aged 17 had won £1m on the lottery. She was unsure what to do with this wealth although a top of the range car, a holiday with all her friends and a shopping spree were all on her list.
When I received this cheque this morning I had similar dilemmas. Goodness me what could I do with this unexpected windfall? I have no idea why Iwas sent this princely sum.
And I do worry about any financial company who sends out a cheque for 1p by first class post at 60p a time.
