We need earplugs because of neighbours on on side - but it's not their fault and we're truly sorry for them having to cope. Their youngest son (5) is severely autistic. Not quite non-communicative, but a nightmare to live with - they can't go on holiday, even though they bought a caravan and accustomed him to it, because as soon as the surroundings were different he threw screaming tantrums and ran away.
They are trustworthy and pleasant people, even help with our snow-shifting in winter, but there are times when the furious screaming from the child gets somewhat trying to live with. We cross fingers and hope for the best, at least the boy now recognises us and doesn't sound off if we leave our house and he sees us. One day they'll have to stop him running round in just underpants if he doesn't want to wear trousers - that could be fun. :(
