I was about to go to bed. Noticed outside was a girl aged 5-7 wearing a Halloween outfit with several of those one off glow necklaces (that made me draw attention to begin with) with her mum. They were going to paths to houses and knocked on a couple of doors.
Who in their right minds will answer the door that time of night, unless you are expecting it - member of household returning back from work etc or ordering that very late takeout delivery?
Half term was last week here. It's not acceptable for a young child to be out that time plus some of the streetlights switch off at 11pm. It doesn't matter if its half term or not,
If the mum was working until, say 9pm, then she should arrange with DD's friends' parents to go round with them. If that is the case that she finished work, who looked after DD after school?
