Infinity.

One great thing of being a parent is having great discussions. It took me many years to accept that time doesn't have a beginning, nor does it have an end. It took so long because I wanted my mind to be able to realize, feel this infinity. Grasp it's essence. And after a long struggle I finally accepted that there are boundaries to what I can do with my mind. I came to terms with the idea that it's enough to be able to know the essence of infinity without being able to feel it. There never was a beginning in time, nor will there ever be an end. And there never was a beginning in space, and never will there be an end.
And then my son came. He was reading a script about time and started talking to me about it. "It feels strange in my head" he said, and then that he wouldn't accept it. He wouldn't accept that there never was a beginning. I let it rest. We'll see when the subject comes up again.
