參考答案:Puppy love is an informal term for feelings of love, particularly between young people during adolescence, so-called for its resemblance to the affection that may be felt towards a puppy dog. The term is often used in a derogatory fashion, describing emotions which are shallow and transient in comparison to other forms of love such as romantic love.
Puppy love, also commonly known as a "crush", can also describe the love or lust of a child or adolescent for an adult. For example, a student being attracted to their teacher. In this case, the term relates an infatuation which is not reciprocated. The term may meet with resistance from some young people as patronising and belittling of genuine emotion (see the pop song Puppy Love below).
During Elizabethan times, it was known as 'calf-love'. A prominent example can by found in William Shakespeare's play Romeo and Juliet, in which a young man, Romeo Montague, is infatuated with a girl named Rosaline before finding true love with Juliet Capulet.[1] In the second act, Romeo is chastised by his friend Friar Laurence, who claims his new love for Juliet illuminates the shallow nature of his feelings toward Rosaline:
“ Holy Saint Francis, what a change is here!
Is Rosaline, whom thou didst love so dear,
So soon forsaken? young men's love then lies
Not truly in their hearts, but in their eyes.[2]
”
