Mirror

The space in the mirror has to be filled to see your image. The space is the seat of invitation for the body to reflect but the body cannot take away the space. The room is nothing but space, you bring furniture to occupy the space but the space lies under the furniture like you bring light to see the darkness. Suppose, You’re experiencing darkness in the room is because there was no light but the light cannot take away the darkness. The darkness stays below the light. Example, During Power cut-off, If you lit a candle the darkness never totally disappears but you still find it in the bottom of the candle.. 

In this world, nothing will disappear but stays underneath. If you remove furniture the space once again gets restored, like you move out of the mirror, you can see the default stage of space in the mirror. The space is full of activity. There is no empty space because matter and antimatter can form by borrowing from space and cancel each other. 

Your spouse asks for a space because you are so long occupying and she wants you to move a little to experience her space. The space was already there in her before she met you. The space cannot be created or destroyed but temporarily occupied.
Your birth and death was more like matter and antimatter and canceled each other in the space on earth.
