I also have the prerogative to reply whenever and to whoever I please, right?
Sure. But when challenged to explain your position, you can:
(1)rise to the challenge, OR,
(2)beat around the bush trying to avoid it.
Else, one would conclude that you did not have any meaningful response to the challenge.
This exchange itself is meaningless. Please answer the questions I posed earlier if you would like to engage me.
You are well within your rights to refuse to. I will leave it at that.
Chao!
