The title says it all. Develop a thicker skin, maybe? I have a very old friend who will always disappoint me if I expect more from her than she is able to give. Yes, she gives a lot more to her family or friends she's trying to impress. But that's her, not me. Most people are heavily invested in their own agenda. Lately am trying not to dwell on these things. Actually it puts me more at peace. Give more, expect less, detach a little. I don't know. I am trying these things but I tend to get clingy and demanding in friendships, I guess. I don't know. Have been kind of off friends for a few years.
