Angry looks can do no good

1 Angry looks can do no good,
And blows are dealt in blindness;
Words are better understood
If spoken but in kindness.
Simple love far more hath wrought,
Although by childhood mutter'd,
Than all the battles ever fought,
Or oaths that men have utter'd.

2 Friendship oft would longer last,
And quarrels be prevented,
If little words were let go past--
Forgiven, not resented.
Foolish things are frowns and sneers,
For angry thoughts reveal them;
Rather drawn them all in tears,
Than let another feel them.
