offering to wash cars?
now I have to say I lol as they were very small and I have a massive van, but this isn't the first time they have knocked.
I did do the 'you shouldn't knock on strangers doors thing' but aibu to think it is unsafe/,
I live on an estate. it isn't one where everyone knows each other, and I do not know these children
I would guess them to be about 5 or 6
