DD 16 went to visit GPs this weekend and her Dear Father was there. He's a father who can't be arsed to see her, she has little contact with him. He bombards her with pictures of what her half-sister has done this week, this hour, this minute whilst spending no time with her. She's not a favourite in the family due to some complex family dynamics despite being a great young lady.
During the middle of a bbq with lots of people all around her dad said to her oh by the way I've had a mole removed on my arm, look. Shows her a small scar. Says 'its cancer, it's not gone away though' then shows her his chemo port - then he walks off and says no more about it!
I mean, can you fucking believe that?!?
And right in the middle of her exams for Christ's sake.
Due to his total lack of interest in this particular child out of the three he's got, we are not on good terms and, thankfully, we normally have to have very little to do with each other, rarely speak etc.
I just don't know what to or whether I should say anything to him such as "You selfish bellended twat, why did you drop the C bomb to your 16 yo daughter then walk off with no further explanation / reassurance / opportunity for questions?" - or say absolutely nothing because what's the point, he's an utter selfish wanker and it won't even register?
