I'm wading in Excel and C++ right now. Each program does tens of thousands of calculations to come up with one number I need. All my boss sees is one number and he can't understand what takes so long. I try to explain, but he can't possibly understand.
All he sees is one number wrong. "It's just one small thing isn't it?" he asks. "You just calculate it, right?"
"Yeah", I respond. "And open heart surgery is just one small thing too. They just cut you open put a valve in and close you up. No big deal."
