Loitering around with a brush? Sorry, but you're breaking the law. If you have a brush, that's okay. If you're loitering, that's okay. If you combine the two? Well... watch your back.
Where were you loitering with your brush, breaking the law? Right outside the Ritz (りつ) Hotel. You'd think that it would be okay since you were staying there, but the law is the law.
