No human motions should be forced or restrained,
Unless the welfare of others is to be attained.
In some general sense, everything I do,
To a limited extent, has its natural effect on you.
By two meeting in the road, one of us must turn,
To let the other pass or his rig might overturn.
By breathing the air some oxygen I must consume,
Also infecting what remains by what I exhume.
When in the market I buy my daily supplies,
That alone has a tendency to make the price rise;
