I walked home on Friday night at 1am in Amsterdam Oost (close to Oosterpark). Within 20 minutes, I was catcalled by at least 10 guys. 3 cars stopped in the street and tried to talk to me. They insulted me and told me to fuck off when I told them to leave me alone. One car even turned around and followed me. Then a guy walked past me and he just grabbed my butt and laughed. I can’t understand how those guys think it’s funny. We need more police patrolling the streets and more education for young boys.
