Disguises by Elizabeth Jennings

Always we have believed,
We can change overnight,
Put a different look on the face,
Old passions out of sight:
And find new days relieved
Of all that we regretted
But something always stays
And will not be outwitted.

Say we put on dark glasses,
Wear different clothes and walk
With a new unpractised stride –
Always somebody passes
Undeceived by disguises
Or the different way we talk.
And we who could have defied
Anything if it was strange
Have nowhere we can hide
From those who refuse to change.
