If I have two objects, Person A and Person B, and I want to know if Person B is facing the same direction as Person A; once I have the vectors, how do I use the normalized vector to show direction?

I've read the math on vectors, but I'm still learning, and I am not understanding how the unit vector shows direction. I know it does, but I don't know why.

One person said they imagine it on the unit circle. I understand how that can show a direction, but what I don't understand is how the normalized vector shows me a direction.

I have seen "http://gamedev.stackexchange.com/questions/82790/what-is-a-direction-vector-and-why-should-it-be-normalized", but I am still missing it.
