Fantastic isn't it. Two people looking at the same thing, whether it is Art, an ideal or concept, music, or just a tree. Many different variations come from two different people. Day by day a single person's perception can change. The same idea, the same item, the same music can change with experience gained or knowledge attained. Concrete ideas.... 2+2=4 ... Simplistic joy in such evident truth..... Will add more thoughts in greater length later or tomorrow.
