Everything that irritates us about others can lead us to an understanding of ourselves.
I know what it means to do a job... I worked in a factory. I respect people in the service industry. What irritates me more is when people aren't respectful. There's a lot of nonsense behavior, especially in a place like Hollywood. The money, the power, they create little monsters.
Where grief is fresh, any attempt to divert it only irritates.
The 'serial kisser' tag that has been thrust on to me is a lame stereotype. It irritates me. Yes, there is sexual content in my movies, and I have never been apologetic about doing bold scenes. But it's not fair to tag me this way because that can be very stifling.
It's a very strange thing for a designer to say, but one of the things that really irritates me in products is when I'm aware of designers wagging their tails in my face.
