Tmes change as do our thoughts.

To be steadfast on a subject

Leaves you open to be wrong.

It will depend on the subject matter.

Have we not, at times, been mistaken

In an opinion we have expressed.

Sure it would be folly to say, not me.

Opinions have no right without proof.

Oft times we express ourselves,

Not giving a damn who we may hurt.

A slip of the tongue, not caught in time,

Has damaged many a friendship.
