AVOID THE DIFFICULT PEOPLE!

OK, so I'm trying really hard to keep from being spotted as narissistic supply by the narcissists out there in the world and I'm getting it, I think - I know what's my business and what isn't - and most isn't...  I'm working on not smiling so much and I'm staying present instead of disappearing - and yet...  I had an encounter today with a woman I'd met months ago because I rented the apartment she had been living in.  She had an ad out saying that she was moving again and was selling off a lot of plants and pots, which I need.  I emailed her and told her that I couldn't make it to her place the day of the sale (tomorrow), but she had said that people could make appointments if the sale time didn't work out.  I told her that today at 1:30 would work - she emailed back saying that 1:30 was OK.  I got a taxi and arrived at her door, only to have no one answer.  I called her on her cell and she said, "No,honey, the sale is tomorrow."  (Oh, how I hate narcissistic sweetness...)  When I reminded her that she had OK'd this time and date, she said that she thought I'd meant tomorrow and she was on her way out the door and was LATE - like I was to blame for that!!!   I came home and read my emails and her replies and I was very clear that I'd meant today - I SAID today.  I remember that the last time I dealt with her, it was difficult, too - so why did I attempt  this again????  I have to keep telling myself that people don't change usually and once I discover that they are difficult, I should just not deal with them again..  Point 4!!!!  Once I know a person is difficult, I should keep my distance.  Lesson learned.
