“In love one should exercise economy of intercourse. None of us can love for ever. Love will be stronger and will last longer if there are impediments of its gratification. If a lover is prevented from enjoying his love by absence, difficulty of access, or by the caprice or coldness of his beloved, he can find a little consolation in the thought that when his wishes are fulfilled his delight will be intense. But love being what it is, should there be no hindrances, he will pay no attention to the considerations of prudence; and his punishment will be satiety. The love that lasts longest is the love that is never returned.”
