Rant coming.
I was on the train this morning and there was a man telling another man exactly how he felt with the CSA.
Amongst other snippets he said;
The child was an "expensive mistake".
He didn't see why he should pay £50/week
He would advise only giving a basic salary to the CSA, see if you can get away with paying less. 
And
"She has all the money and rights and none of the responsibility."
I wish I'd been brave enough to confront him, but a packed commuter train is probably not the place to start an argument. There were plenty of dirty looks being thrown his way, from men and women, but what a low life scumbag.
So Aibu to think that poor child to have that as a father.
