Saying that negotiating with the EU is completely different because it is a different negotiation is a bit much; just because you don't like the negotiation we're doing. If you watch the playground bully punching someone; when you are next to face up to said bully, being punched is not exactly sensible is it? You kick him in the nuts then you talk to him. At least if you have any sense, you don't have to be the size of the playground bully to do that.
As for being unimpressed because someone wants to crash the car, just because you are driving it somewhere else today and they don't like where you are going? Yep I reserve the right to be pretty unimpressed with that behaviour.
