Why did I choose this poem?

The first time I read one of Sor Juana's poems, I had recently finished the secondary school.
I got very impressed by the way she writes. She says what she thinks without being afraid of any punishment or censorship, in a time during which writing was forbidden for women.
This poem refers to jealousy, a feeling that usually interferes with lovers causing doubts, uncertainty and unhappyness.
It likes me because of its simplicity and rhythm.
