I think you do what you can, where you can mate…..that’s the honest truth of it.
I always warned my kids off hanging around with ethnics and scumbags from no age, you just hope it gos in the nut and sticks there.
Thankfully, they have never had odd marks in their social circle.
I’ll also add, that no matter what age if your instinct tells you something, anything, is wrong then you step in, no matter what aggro it may cause because it’s almost inevitable you won’t be getting thanked for it at the outset.
I have daughters of 19 & 18 and I have been told to mind my own bus
