Why is the main question

The question is not who, what, which, or where, It's why. Why does fun always seem to end? Why does fun never last? Does fun end because it has to go away to live or just because there has to be more, different, and new fun in life. Why, why is there always endings in life? Is there endings for new to come? Why, why does no one ever stay in someones life, why does everyone not always stay in life they lose connection or just... ye. Do people always eventually leave to make room for new people in life or just because?And why, why do sometimes even the most sentimental, and emotional people not show their emotions is it because they fear showing it or because the emotions are just too strong. And WHY, why do the most sentimental, and emotional people tend to cut people out of their lives especially near endings is it because they just value everything/everyone in their life too much to say goodbye or is it because they miss everything/everyone in their lives too much. And WHY, why do the most Sentimental/emotional people even when they want to cry they cant even with the people they are closest with and most comfortable with. Is it because they hide their emotions, or is it because they want everyone around them to be happy when people around them are not happy or is it because even though they know that to take care of others they have to take care of themselves first although they secretly want everyone around them to be happy.
