Puppy love may indeed feel like its deeper emotional cousin called "true love," but it usually has a fleeting quality which keeps it from developing any further than a serious crush. Puppy love often starts with a one-sided infatuation, perhaps for a seemingly unapproachable classmate or an attractive teacher or other authority figure. For the smitten one, these feelings of attraction may be very intense indeed, and create the sort of distractions and obsessive thought patterns of true love.
