"If you love without evoking love in return – that is, if your loving as loving does not produce reciprocal love; if through a living expression of yourself as a loving person you do not make yourself a beloved one, then your love is impotent – a misfortune." - Karl Marx ( #BOTD)

I bet you didn& #39;t know "Economic and Philosophic Manuscripts of 1844" contained such romantic lines like these!
