The contrast effect can ruin your whole life: a charming woman marries a fairly average man. But because her parents were awful people, the ordinary man appears to be a prince. One final thought: bombarded by advertisements featuring supermodels, we now perceive beautiful people as only moderately attractive. If you are seeking a partner, never go out in the company of your supermodel friends. People will find you less attractive than you really are. Go alone or, better yet, take two ugly friends.
