What is the difference between someone who is truly toxic and someone who is just a depressive?

I draw the line at bad behavior, I guess. This person has never been rude to me. He shows up when he says he will...and we alternately treat one another to lunch or coffee. We always go to very nice places so eating out is a pleasant experience.


I think he is just a "sad sack."


I wouldn't say he is toxic. I got rid of all the really toxic people in my life and it feels good. This person is somewhat marginal, I guess.

I'm waffling!
