Are you for real or are you playing dumb? If I pay you $70K for an empty box and you send it to me what I received is that empty box. I didn't receive $70K. I gave up that money. So, you must be playing dumb because no one can be that stupid to claim that they received $70K when they actually gave up that money.
I respect your opinion. Yes. Only people with stupid thoughts can do it. If we think too much about the empty box, we will never feel the contents of the box and it will always be empty. Can you see visually what the air actually looks like? We can only feel it when we inhale and exhale.
