عندما تتمنى شئ وتتيقن أنك ستمتلكه ... وفجأة يصبح سراب

عندما تشعر أن السعادة أصبحت بين يديك ... وفجأة تراها بؤس

عندما تتلون الحياة بألوان الفرح ... وفجأة تصبح الحياة بلا ألوان

عندما ينبض قلبك هاتفاً أحبك ... وفجأة يصبح هذا القلب

قلب على فراش الموت

انتظروها ..... حياة قلب من الميلاد حتى الاحتضار
