It seems to me, broadly speaking, that there are two kinds of people.

I find myself aware, more and more, that some people leave me energized and optimistic after we've spent some time together...

and other people leave me feeling negative and exhausted.

In other words, some people are beneficial, life-enhancing, truly sentient; others are toxic. Parasites.

In the Hindu tradition the former would be called sattvic, though I forget the word for the negative soul-sucking types.

To my deep sorrow, friendly, charming, outgoing folks are not always the sattvic ones. And the quiet shy ones are not necessarily downers. I suppose that's well known--smiling faces, covering a toxic way of being.

Even in my immediate family, some are life-enhancing, others essentially poisonous.

If you live and work in close proximity to people, without much choice about it, I guess the only thing to do is to limit your contact with the negative, exhausting types as much as possible.

And get out and enjoy fresh air and nature when you can.
