Was walking with my DD and my DD friend onto my drive way. They are 6 A group of boys went by on bikes. They were singing loudly and my DD friend told them to ‘shut up’. One of the boys on the bike said ‘don’t tell me to shut up or I’ll come back to your house with a hammer’. I didn’t say anything as obviously they saw we were walking up the drive way and didn’t want to escalate it in case they came back. They are older, I think maybe early secondary age. I vaguely know where they live. Would you report this? I found it threatening especially worse as it was said to a young child.
