Sonnet
138
When my love
swears
that she is made
of truth
I do believe
her though I know she lies,
That she might think me
some untutored
youth
Unlearned in the world's false subtleties.
Thus
vainly thinking that she thinks me young,
Although she knows my
days are past the best,
Simply I credit her
false-speaking tongue;
On both sides thus
is simple truth suppressed.
But wherefore says she not
she is unjust,
And wherefore
say not I that I am old?
O, love's best habit is in seeming
trust,
And age
in love
loves not to have years told.
Therefore I lie with
her, and she with me,
And in our faults
by lies we flattered
be.
By William Shakespeare
