Laughter and Tears Balance the Life of the Universe
If laughter you mean is happy, while crying is sorrow, then for me laughter and cries is a necessity in the living space.
There will be no weeping of laughter without the tears we have ever experienced, and we will not encounter a single cry without the laughter we once experienced.
Both complement each other as love and pain, joy and disappointment, or joy and sorrow, because that's how God describes the color of life to every servant of His.
And God did not create something without a reason, even when God created the color of life. Maybe God miss?
When God gives a carving of laughter or when God gives a splash of tears at a time. Has his servant been grateful for the laughter and tears that God has given? Has His servant answered His longing?
Sometimes we cry in laughter, and sometimes we laugh in tears. Over time, both will be longing.
Slowly it will leave a scratch on the memories carved by the sharpness of the knife of time. All will go back into His arms, an everlasting longing.
