I miraculously came in contact with another human since I last posted and managed to bring up these topics of nothing and everything. She reminded me what an asymptote was when I explained how another person was trying to claim +∞ = 0. This led me to discuss negative numbers. That's when we realized what distinguishes −∞ from +∞ is 0.

Girl: So 0 is finite
Me: Then the concept of nothing exists relatively

It seems too easy so I'll just wait for a mathematical smack down.
