wisdoms of infinity

My grandson and I where building plus plus together this weekend. He asked me what I was doing and I answered that I was making a plant. I then asked him what he was doing. -I am building space he said. Ok, what does space contain? I asked him. His answer was as obvious as it was immediate. -Everything I dont know he answered me.
And a few weeks ago, he built a sand castle with a sleeping queen in the house in the middle, surrounded by a “castle wall”. He said then, -Tobbe and Lotta with their kid live in a small village there.
I guess personal space and the person that is to become its inhabitant is making room for itself ..
