There have been a lot of threads recently about friends. I certainly haven't had many over the years. Recently I asked a friend for a favor, and they flaked on me. I gave advanced notice and let them know how important it was to me. If I had waited a really long time (I only waited around 4 weeks), they maybe would've done it. In the old days I would write this friend off but I just reluctantly did the thing without my friend's help. I feel bad still - like maybe I didn't wait long enough, maybe I sounded passive aggressive when I let my friend know I was planning to go ahead without their help. I know I did better than I would've in the past but maybe not well enough. I am sure this is a BP thing. So what's the best way to manage expectations and maintain relationships?
