To me this part was particularly telling
If the mother felt uncomfortable, for whatever reason, all she had to do was say "No thank you, we're fine", same as for any offer of assistance which isn't required. It didn't need this drama, this circus surrounding it.
This reads as if it was only the mother that was freaked out / creeped out / embarrassed and not the child.
It also places the level of harm at 'the mother feeling uncomfortable', the child was apparently, at worst, entirely neutral.
Also the use of the term 'the mother' seems a little odd to me - as if 'the mother' is some sort of an object rather that a concerned mum. What's wrong with 'the girl's mum'?
It makes me think back to the earlier linked twitter post expressing the opinion that 14 year olds (minors by law) were practically fully grown and, by trying to protect them, parents were guilty of infantilizing them.
As I said in response to the previous poster - this all seems a little like a PIE or abuser's justification of why minors should be treated as adults. To me, any attempt to ignore, circumvent or minimize safeguarding should be treated with suspicion.
I view David Tennant's 'You are safe with me' badge as a similar attempt to circumvent the rules of safeguarding.
Where some posters seem to think that this drive by scolder is child with a child's opinions, the comments seem much darker and more calculated to me.
