Harassed/Followed at CFD

When I was in high school, I would go to Car Free Day every weekend. But that one time I was too tired to run because I had a long day the day before, so I decided to just walk alone, my friends ran ahead. This one guy rode his bicycle up to me, and got off his bike, following me walking on the road. All of a sudden, another guy, who was his friend, rode up and got off too, also following me while I was walking. Then one of them shouted, “Ada cabe nih nyet” and then his friend replied and said “cabe strawberry nyet” (because I was wearing a red shirt). I ran to find my friends and I told them about it and my friends accompanied me the rest of the time.
