If I call a plumber and tell him I need service at an "address". Then he calls back to say he's lost, which of these would be grammatically correct to say?
My house is second on the right.
Our house is second on the right.
The original conversation was between him and I, no one else involved. The house is owned by my wife and I. If I say our its because its not just mine but he only knows of me so is it ok to say my house?
