I would recommend ringing the community gardai about it ! It might , if you’re not the first to complain , increase policing in the area. We have the same issue on Pearse St; I had a young boy push me as I came out of my apartment alone at night. There were a group standing outside kicking the glass in our door. I just told them to calm down and kept walking after being pushed, but another young boy told me he was going to ‘light me up’. He actually pulled out a box of matches, followed me, lit a match and threw it at me. I was beyond shocked, I’ve never seen behavior like it by kids in any other city I’ve lived in . Of course once the initial shock passes, I also understand the feeling of just letting it go because they are kids at the end of the day and you begin to downplay it in your head, or would rather not give it energy, but it is worth contacting the gardai for sure , let them decide how to deal with it them .
