Answer:
like everyone,she walks on the ground
Step-by-step explanation:
This is one of the most famous Shakespeare's sonnets, "Sonnet 130".
Interesting thing about it is that in a way mocks romantic poems of the period. The common style of such poems is that they center around comparison of women with natural beauties, flowers, goddesses etc. The authors' love interests were highly idealized and shown as perfect, out of this world beings.
Here, Shakespeare fights against this in a very funny manner. He constantly, throughout the poem, gives a realistic description of his lover, rendering her unable to compete with natural beauties, smell of perfume, sound of music etc.
However, that doesn't mean he doesn't love her; he loves her the way she is - as real and as imperfect as one can be.
In lines 11 and 12 the author basically states that he has never seen a goddess walk, but he is sure that his mistress walks in a quite ordinary manner, just like every other woman does.
This line is just a logical sequel to the idea expressed in the previous lines.
