I can't see a human aura that clearly.

But sometimes I can feel it.

It can be broken down into three types; positive one, neutral one or negative one.

Mine is rather positive than neutral though, I know I'm a bit stagnant nowadays.

It's really interesting that people of each type gather or attract to each other.

Someone whom I've known for years suddenly visited me the other day.

That person seemed to have been affected by negative side until recently, but as long as I can feel, that person is now trying very hard to come to rather positive side of neutral.

We kind of attracted to each other under the condition carrying a similar type of aura, that's why...
