I agree with Cat that the matter is far from black and white. I also agree that the letter wasn't mean. In fact, I bet the writer(s) agonised over how best to word their message to be sensitive to the fact that they knew the little girl was autistic whilst conveying that they need to be able to work/live too. I agree with Redballoon in having sympathy for both neighbours. I certainly don't agree with Elishatraill that this was an attempt to shame.
