It's a stepping stone between diapers and grown-up clothes. Due to some obvious physiological differences, Pull-Ups are different for boys than girls. This may be a good idea, but it's the patterns themselves that bother me. I find this interesting. Obviously enough, they were following social prejudices about what patterns the kids will prefer, or more likely, what parents think their kids will prefer.
Girls dress in pink and like flowers, boys dress in blue and like science.
It's a subtle issue, but in my opinion a real one. Even in these enlightened days, there are far fewer women astronomers than men. Women drop out along the way to a career in astronomy . Again, there are many reasons for this, but women interviewed say that they get tired of fighting the sexism and prejudice of male colleagues, and that the male-dominated committees tend to pick fewer women for advanced positions. Even in astronomy, which studies the far reaches of the Universe, women have a glass ceiling.
