Numbers - Realistic or Relativistic

Numbers - The key word is numerical representation of what you see. When i see a tree, i write "1", when i see "2" i write 2. That is how we are taught right from the day we went to school. So we can say number is the outcome of what you see. So blind people do not feel Numbers??????? They do understand, so the number has got nothing to do with eye, So has it got somethin to do with brain or i probably think mind? Lets consider a scenario, suppose i am observing "a tree" with one of my friend and suppose this person starts "counting the leaves" of the same tree, now each one of us have different numbers registered in our brain, In my brain the number that has been registered is "1" as i am just observing the tree, but its not the same with my friend as his focus is on the "number of leaves", but the point we need to keep ion mind is that it is the same tree. So from the above observation, one thing that can be concluded is that "Numbers are focus dependent".So now the problem takes a different direction, i.e. is "FOCUS" real or "relative". As we all know from Special theory of relativity that focus is "relative", i can conclude that the numbers are "relative"
