We wouldn't enjoy the sunshine
If we never had the rain.
We wouldn't appreciate good health
If we never experienced pain.

If we never shed a teardrop
And always wore a smile,
We'd all get tired of laughing
After we had grinned awhile.

Everything is by comparison ...
Both the bitter and the sweet,
And it takes a bit of both of them
To make our lives complete.
