Appreciation of Portuguese Sonnets

My wife swears that she is loyal,

I believe her (although I know she is lying),

Make her think I'm an ignorant child,

I don't know all kinds of deceptive activities in the world.

So I fantasized that she thought I was young,

Although I know that my prime is gone forever;

I naively believe her glib:

In this way, the simple truth is covered up by both sides.

But why doesn't she admit to lying?

Why don't I admit that I am old?

The habit of love is that even trust becomes fraud,

Old people are most afraid to mention their age when they fall in love.

So, I lied to her, and she lied to me.

Our love delights in cheating.
