Hi, one day I took a tram with a friend and two gypsies boarded her. When they performed, they told me "What are you doing pi * o". I took it with humor and laughed. The next day we met them and they asked if it was us. We ignored them and she said the same sentence again. About a month has passed and a friend met them at her block of flats yesterday. They asked her if it was her and said "no". Then she met them twice more around our blocks of flats (we have blocks of flats next to each other). I have a feeling they want to beat me or do something to me and I'm scared. Would anyone please advise me what to do?
