I was really frightened at first, but I calmly explained to him that I was working on an art project and he didn't seem to mind and so I went ahead and put my camera on self-timer and ran back and forth.
Fiquei muito assustada, no começo, mas expliquei a ele, calmamente, que estava trabalhando num projeto artístico, e ele pareceu não se incomodar, então continuei e coloquei minha câmera no modo self-timer e corri de um lado a outro.
