True - sorry, I am just having a bad day. I will post about it elsewhere.
The truth is, I wish I was able to be assertive rather than aggressive, but I often find keeping control very difficult.
I genuinely do get very impatient with submissive people though - they just get under my skin & really irritate me. But passive-aggressive is much worse than genuinely being submissive, becuase it is false & fake.
