A problem needs solving. I puzzle out the possible solutions. It's sticky and messy and other people need to be considered. My imagination kicks in and now I'm picturing the discussion I'll have with the people involved. Sometimes I'm arguing.
It's funny how in these imaginary conversations I am always eloquent and convincing. It never works that way in real life. It is always so disappointing to actually have the discussion and find that people aren't sticking to the script. I had it all thought out, therefore I might be right.
