I've just been to pick my DC up from nursery and there was a small crowd of teens, maybe aged 12-14 standing where I was parked. They were shouting and swearing very loudly and repeatedly at each other which my poor DC had to witness. I lost it when one of them shouted a horrible racial slur right next to my child. I said 'Please go and swear somewhere else', to which they then started heckling me!
As they walked away I took a photo as we were directly outside their school and they were in school uniform. Can I send this to my head teacher, or am I being unreasonable in that I shouldn't have taken a photo of them?
