Looking at an inanimate object it is impossible to see the connection. Inherently, it feels like no connection exists except that we both are here at the present time. It seems separate from me. There is space between. Someone could pass through the air between us and nothing would change. I would still be here, and it would still be there. Or would it?  If there was a person standing between us how could I be certain that it was still there? If someone sits on the other side of it and tells me that it is still there then they see it too? So how could it be just me looking at it that makes it so? I asked my friend if she saw it there on the table, she confirmed. Then I asked her to describe it. Everything she described was in accordance with what I believed that my own eyes saw.  

If my eyes made that up, then they made up my friend too.
