Quantum of Light and my Parrot.

Gentlemen
I have only two questions:
First -
Didn’t my parrot fly to you?
Second -
Why does everyone say that all movements are relative
if the speed of quantum of light isn’t relative but
it is an absolute constant in absolute Vacuum ?
P.S.
You can easily find out my parrot. It studied only
two sentences: ‘ there is no absolute movement ’,
‘ there is no absolute reference system ‘

P.S.
‘ All these fifty years of conscious brooding have brought me
no nearer to the answer to the question, 'What are light quanta?'
Nowadays every Tom, Dick and Harry thinks he knows it,
but he is mistaken. ‘
