DD (8) was playing in the garden with our neighbours daughters (6&4). They were sat at the end of the garden on a rock messing around when some teenage boys walked past on their way home from playing football (we live right next to the park, road goes past end of the garden). I saw them walk past and say something to the girls, then one turned back and held out his phone for them to see. The 4 year old started laughing, she and her sister walked down the edge of the neighbouring house talking to them, DD hung back. Then all the kids ran back along the side of the house.
I asked her if she knew the kids, she said yes. I asked who they were and she said she didn't know them. I asked what they'd shown her on the phone and she said a picture of a man with a naked willy.
FGS why??? Why do teenagers need to show this stuff to young girls? What do I say to her?
