It's crazy just to think about the possibility of everyone being frozen in time and me having the whole world just for myself. Haha. I think a week would be more than enough time to get up to some craziness.
First, I'd go to a car dealership and grab a vehicle so I could move around freely and explore whatever I want. Then, I'd head to Rio de Janeiro to visit places I've always wanted to go but fear of violence has held me back, like some of the favelas (Rocinha and Complexo do Alemão).
Embracing the adventurous spirit, I'd also use buildings and streets as a huge canvas and create various murals with paintings. I'd go to various fancy and expensive restaurants and try all sorts of foods.
And, I won't be hypocritical and pretend I wouldn't commit some crimes!! I'd go to electronics stores and grab some devices for myself too - don't tell the police, please. Hahaha.
