Reflect on the type of face you usually have a crush on.

Go back in time, year by year, and identify one such type you encountered per year.

Go back further, to your early childhood, doing the same.

You will find that that type of face is directly related to a young father, a young mother, a young father's friend, or a young mother's friend--and someone who carried you, played with you, or smiled at you during a happy occasion, such as a children's party.
