> what is "half"
I know that the concept of fractions is going to be difficult for someone so PDD that he can't count, but I'll try to explain.
You say many things which are the complete opposite of other things you say. As they are entirely contradictory, only half of these statements can be true. It is impossible for things you say that disagree with other things you say to both be true, so one of those two things is untrue. One out of two is fifty percent, a half.
