My DD is 12, diagnosed ASD, mainstream, Y8. There is a girl, "Gertie" (name changed), with whom she had been friendly since Primary. In Y7 they started at our local secondary together, and Gertie was in our house 4 nights a week after school, including having her dinner, and being driven home by DH. DD was never invited to Gertie's house after school, but I put this down to the fact that her Mum is a childminder, and has a houseful already. I went with this, because, as other parents of autistic kids will know, it is not always easy for them to make friends.
Towards the middle of Y7, Gertie sent a text out of the blue, saying that she thought they should not be friends any more. DD was upset for a day or so, but a) these things happen/people move on, and b) the black-and-white of autism kicked in so DD became matter of fact, "OK, Gertie doesn't want to be my friend, I have others". She does, in fact have a lovely but very small group at school.
Now in Y8, Gertie has started coming home (occasionally) with DD. This only seems to happen when her family are unavailable to walk her home from school (where her father works), and there seems to be some expectation that DH will take her home later, OR that my DD will walk halfway with her, and then Gertie's older brother will meet her. She is the older of the 2, so it seems ridiculous that it's OK for my DD to be out after dark alone, but not Gertie. So I have not been as welcoming, no offer of snacks or dinner, and please phone someone to come and get you. I feel we are all being used. AIBU?
