TT gie it a bye. I have known Robert since he was a nipper and what he doesn't need now is a twat like you defending his corner.
As you say rightly (cannae say that very often) he is a fully grown man and can argue his case if he felt the need, but obviously he doesn't.
I wish Robert all the very best in his new appointment.
Whether you agree with the decision or not just get over it.
