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 untutor'd youth,
Unlearned in the world's false subtleties.
Thus vainly thinking that she thinks me young, 5
Although she knows my days are past the best,
Simply I credit her false speaking tongue:
On both sides thus is simple truth suppress'd.
But wherefore says she not she is unjust?
And wherefore say not I that I am old? 10
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 flatter'd be.
