Помогите пожалуйста перевести:

"Not that he didn't think of things to complain about, but that was another matter entirely that had everything to do with he being as insufferable prat"

UPD от сегодня:
помогите плз с еще одной фразой, вогнавшей меня в ступор:
he could read a whole lot in his gaze at that moment, and just about every word would have been considered treason from anyone else.
