I don't think it even occurred to him to say sorry to me.
Or that he even owed me an apology.
But that is him - he is Mr angry and goes around reprimanding others about their behaviour, but he never considers his own behaviour.
I have silently waited for them to realise I do not want be in his company.
It has taken nearly a year for him to see all is far from normal.
That speaks volumes to me.
