A curved Parallel?

My math teacher said that only straight lines can be parallel.
I asked why can't straight lines? She said "because that's how it is."

I dislike this.

Why can't a circle within a circle, where the centres are the same only with a differing radius be parallel? Is a helix parallel?

holocaust never fucking happened you retard. it's just a myth fabricated and perpetuated by jews to enduce sympathy from the international community while they rape palestine. now that they have gone too far, the truth is slowly coming out.
