There always has to be a flaw, always. Nothing can be absolutely perfect, it's basically impossible in this world. Nothing and no one will ever be perfect. It won't ever let it happen, or perhaps perfection doesn't and will never exist and is just a mere illusion and desire of the human mind. I don't and won't waste my time on trying to achieve this illusion of "perfection".
My view and definition of "perfection" is what seems the most attractive to me and what satisfies me the most.
