I have done pair programming with a junior partner, and I found it extremely beneficial. Taking the time to talk out my ideas and logic invariably helped make them clearer in my mind and realize pitfalls much sooner than I otherwise would have.
I had to explain things clearly and logically, and he was bright enough to ask good questions and point out typos as I was coding.
Just in case anyone is wondering how true this is, about 10 years ago, an Australian TV anchor decided to keep wearing the same suit and see how long it took people to notice.
After a year, no one had mentioned it.
That said, I agree with the man’s statement that it would overwhelmingly be women who criticized other women for wearing the same clothes.
