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...
