For example you could put it in a safe that is hidden behind a painting. Tell me how you would hide your money and keep it safe? And what could you do to give the police proof that someone robbed your home so they can arrest the robber that robbed you? Tell me how you could get proof to give to the police? And if it was you that was robbed how would you feel? The dog food cost my nan alot of money. And money is the root to all evil.
