Honesty, I'd try to have my family set. I would pay for my sibling to go through college because I know she's reeeeally worried about being in debt and I don't want her to worry about that. I'd buy my mom a nicer house if she wanted one or a better car or just take her on a shopping spree, she spends all her money on her kids and I think she deserves a little in return.
Oh and I'd buy a giraffe. For sure.
