YABU - He is just an adorably bumbling fool who can't remember important information that his very important job necessitates him being able to. Or even seemingly use a post it note, notebook, database or a competent member of staff to help him do so. No, just totally fine to forget stuff.... ooops sorry!
kinda like if any of us were to make a mistake in our jobs that was really important, repeatedly lie about it until called out and then think that saying whoops sorry I forgot would be a totally fine defence? and not just make others question our competence for the role?
or that if someone on Universal Credit forgot about an appointment then they wouldn get total sympathy and not their benefits stopped? or that if in court it would be an infallible defence to say sorry, that you forgot that something was illegal? and then we'd all move on.
YANBU - is it just me or do you feel like you're going insane? what is happening in this country.
