It takes a loving heart To hang in there and fight When love has gone awry And you long to quit. It takes a loving heart To admit you've made A grave mistake And cannot keep a promise. It takes a loving heart To hide your wounded pride, Forgive, and start again To mend a tattered marriage. It takes a loving heart To know When love has flown And it's time to leave. It takes a loving heart To pretend that you will be fine And smile An you watch him go. Only a loving heart Knows how to do these things And only a loving heart Knows when.
