Girls Wear Pink

Okay, so I'm the mom that feels like I can put my baby girl in browns, greens, yellows, etc. It doesn't always HAVE to be pink. But, what I do not understand is when my little girl does have pink on - why in the world do strangers constantly say, "oh, what a cute boy you have" or "how old is he"??? Are people just that non-observant? Addy had a bright pink shirt on today, not even pale pink, and three people at Kroger called her a boy. Now, my baby may be a baldy - but seriously, would I dress a boy in pink???
