It takes two to reach a point

What makes life tough? When you don't get something you think you deserve. As I age, I fear more and more things. I want less and less. But, it turns out my life becomes tougher and tougher. I don't know why. And I don't know if I will figure it out one day. Some unwelcome events came to visit me these days. I am like a scared child who just wants to escape from these events and be alone. I could not justify these events. But, today, when I heard someone said it takes two to reach a point. I suddenly understood. It takes two to make something tough or smooth. You give and take. But when only one gives and one stops giving, it never been able to reach that point.
