I think it is shocking because he is just so fucking stupid and so sociopathic he doesn't understand how to even pretend to be decent to any degree, to him "oh well of course I risk missing the delivery of my premature baby, I got to killstream don't I? Its my thing let me have my space and do my job!" is just reasonable and he is being generous by showing up or trying to at all. He really doesn't get this is the kind of thing people would have swore at and punched out bosses for trying to deny them from leaving to attend, he doesn't get something like that probably rarely if ever happens because you'd look like a piece of shit making a fry cook or an office worker do their rote jobs instead of being there for their child's birth.
To him it is just another thing that you need to give him some leeway to take a piss, or get a quick drink, or chill out for a few hours. Not something he has any strong obligation or desire to see out. What a subhuman faggot.
Hopefully. I cant imagine a child having to be born with that shit cross of genetics AND being raised by two gender confused pedophiles.
