horrible treatment

so my mother is in the hospital, they're preparing to do a colonoscopy, some time this morning,  my dad can't be at the hospital. My aunt can only stay for so long.  My supervisor knows about my mother's hospitalization.  Yet he is purposefully post poning our meeting,  cause the only thing I have to do today is staff.  When I tried to go in to staff, he was on the phone, an extended conversation, now he's just walking around socializing.  He's already considering himself as the next program manager.  what an asshole.  yes, this is where I want to remind myself what a shitty human being he is.
