I am no expert on this subject........but I have come to believe that I know one essential requirement for a lasting relationship. It is laughter

....I'm going through a rather scary time right now, healthwise, and this man of mine

has had me laughing so much today that I've cried. Stress level has dropped to about a 2.....it was an 11

earlier......If I can't laugh with a partner, I'm outta there. And I think that in friendship, it's just as important. I finally quit, reluctantly, a 30+ year friendship, over the increased negativity and gloom and doom......she used to be so much fun and now I feel like I've been to a funeral when I see her.
Any comments?
