Hypothetically speaking: it's the 1920's, you just had a baby boy, what color booties would you get him?
WRONG! According to Wikipedia: "Despite being widely considered the color of females, before the 1930s, pink was considered to be a color for boys in America. Because pink is a watered down version of red, it was considered a color of power and strength, as red is still today. Blue was for girls!"
So there...You learned something new today...I keep telling you, I'm not just a pretty face ;-)
