I have a great deal of respect for people who can walk into a code review and look at their own code objectively as community property.
I had to.
I was doing Y2K work at the time. The code I wrote wasn't really mine anyway. So, code review was the final acid test to see if what I was sending out was actually correct in every way and didn't cause any problems. In that environment, you quickly learn to disassociate yourself from your work. Otherwise, every question on the code can feel like a personal attack. I've watched that happen too.
