I came to this thread to make a similar point. There seems to be an implication that the activities being espoused on the girls life cover are less worthy than those on the boys life.
Like the author came here to say earlier in the thread, the problem is when the messaging becomes pervasive and people say silly things ‘all girls should like this’ and ‘all boys should like that’, and people sometimes feel trapped by their genders.
My life and my experience is so stereotypically female and I honestly have no idea how much of my life I chose and how much of it was chosen for me!
