"Unrequited love is way underrated. It's kind of like smoking. Ultimately it's bad for you, especially in the long term. Both are bad for your health, make you "smell" worse to others, and cause you to pick up annoying repetitive habits, whether it's constantly wanting something in your mouth (smoking) or anxiously checking e-mail (unrequited love). But on the other hand, both have a certain glamour, give us something to do with ourselves, and have a huge deserved mystique and romantic history behind them. Smoking gets you outside where as otherwise you might stick yourself in the office all day, unrequited love gets you to write amusing bon mots where as otherwise you might write nothing but pedestrian e-mail.
