Tsuga - she might have a future in procrastination of the next subject is what it is ;)

Purple Owl - I have no idea. That's a good question. I will ask her!

That one stumped her for a bit! But then she came up with the idea that yes, in theory, after you have counted all the possible things in the universe - thoughts, people, items, etc. - you would come to the end of numbers, the biggest number. I asked her what if I have just 1 thought after that, like a "Ha, I just counted all the things" thought. But she said that wouldn't count because you would have theoretically already counted all the possible thoughts.

This doesn't solve the philosophical part, but she may be interested in a Mile of Pi
