Most boys like some traditionally girly things.. more or less depending on the child.
I'm not one to deny that there are average differences between the personalities of boys and girls. We aren't all blank-slates that are interchangeable, and most parents see early on the "average" differences between little boys and girls at that age.
But those differences are "average" differences, generalizations, and it is very very unlikely that any boy or girl will conform 100% to the most boy or girl expectations (unless they are forced by parents...)
My son is a good example, in most ways he is as "boy-ish" as they come. Swords guns, soilders, heros, battles, monsters, mess, mud, football etc. all your stereotypes...
But then on the other hand he loves making jewelry and playing with sparkly gems, and his right now he really likes pink+purple things... He asked to go to a little craft place that makes bracelets... all girls except him. had a great time. (then came home, and back to monster battles...)
For older generations, I would just smile and ignore.
