My DS is 11 and where we live there we are in a semi detached and in the other half there are 2 boys {5 and 3 year olds}
We share a front garden with them - it is down an extremeley long driveway away from the road
We are the only houses here apart fom 1 bungalow with a man in - but he has a separate garden and entrance iyswim.
And these boys are always knocking on the door asking for DS to play with them.
He is used to playing with little ones cos I am a childminder.
They idolize him and when we go past their house and they see us they are up at the window waving and calling out.
I don't have a problem with it and DS enjoys playing with them - they play imaginary games and pretending they are going on expeditions or play football or collect conkers.
BUT they are friends of ours too iyswim
I wouldn't feel happy if we lived on an estate and he had gone off somewhere I didn't know where or with who.
AND HE NEVER CALLS ON THEM -- they always call on him
