Noisey teenagers are neighbours of me? Yes, if eg:neighbour is a purely geographic / spatial / housing arrangement relationship. Of course (like 'likes'), being a GOOD neighbour is sadly not symmetric. Alice can be a good neighbour to Bob without reciprocation. But that's a different relationship really. We might also say that eg:good_neighbour is a subPropertyOf eg:neighbour since whenever someone is someone else's eg:good_neighbour, they have to at least be their eg:neighbour... Dan
