What would you do with your winnings?
Write "You're a fucking asshole you stupid ****! See? I win in the end ya bitch" on a copy of my lottery ticket and send it to my old boss.
Sorry, sorry. I hate that woman.
Ok, back to happy things.
I'd make sure my family was taken care of. Bills/debt/mortgages all paid off. Or buy them their dream home. Dream cars too. Why not? They've all been there for me so I'd want to make them happy. Set up accounts for my niece and nephew so they'd be set for anything they needed too, like college.
And I'd buy myself a nice home somewhere. Nothing too crazy but just nice. And then I'd travel and see the world!!!!!
