Traveling in Chile - The story behind every graffiti in Valparaiso, I remember seeing a few girls in the graffiti two nights ago, I used to yell at them, but I really want to know why they are graffiti. They speak Spanish and their English is limited. Interacting with each other in the body language, knowing that they are going to graffiti after work. I saw a girl who was crying with graffiti and later learned that her mother had died. To graffiti is to express your emotions. (Although I didn't see the works they formed in the end, they made me know exactly what each graffiti work has. They have different meanings.)
