That's the key point. I've observed that ones tend to want one things and the others tend to want other things.
Of course there's cultural intervention, people do not live in bubbles, but it's much more subtle and, I believe, innate than what you think before having children (one data point: my daughter that I swore would never wear pink, actively prefers pink clothes, she wears other colors as well, but given a choice, usually chooses pink and from a really early age)
