When I was a kid, I lived in a house with an address I'll call 12345 Foobar Rd. Just down the block, there was a house whose address I'll call 12345 Foobar Ct.

When I was a kid, I lived in a house with an address I'll call 12345 Foobar Rd. Just down the block, there was a house whose address I'll call 12345 Foobar Ct. We would get each other's mail constantly. I knew their names just as well as I knew the names of our next-door neighbors.
