You can have it till you don't think you have it.

You lose your right as you use it.

It is kind of paradox, that you can do something only till you don’t do it.

People accuse of others for behaving or doing something in a certain way.

Like Bohr did, he makes some assumptions to postulate a theory. Let us assume A doesn't not approve or like B, behaving in Y manner.

But as soon as A accuse B, A becomes equal to B. So, A=B. B is choosing to behave in a certain way Y, but as soon as A accuse B, and supports other way of behavior; let way of behaving supported by A be X.

Now, as A supports X, A is making a choice. B is also making a choice to behave in Y manner.

If both A and B are making their own choices, A=B. So, if A is like B only, what right A have to accuse or criticize B.

I am not too sure of usage of my word, probably accuse can be replaced by criticize. Also, i am not sure of comprehensibility of whatever I've written above. 

I will take one more example.

Like if a person says someone else to be close minded, then he himself is close minded. Because open minded person should be able to accept others as they are. 

I don't think I've put it up nicely, but still I like fragility of this; to have it, to preserve it, but to lose it as you use it.
