wadr imo this reflects on the self more than on others, and dont get e wrong i have it too ok, but if we were to examine your statement we would find that expectations of others are really what we are talking about, i am sure. Thought you could trust to do what? Better to trust that they will not do them, i guess, see then you can only be pleasantly surprised?
And i guess maybe this sounds like "be cynical" but i dont mean that at all...it's a forgiveness thing. You might be the most trustworthy person you know, but then how do you know ppl, anyway? Briefly, as "other," from a necessarily limited perspective, iow. Imo if you dont trust that ppl will be ppl, and expect ppl to conform to your expectations or else, well...i mean, who is that serving, after all? But hey, not saying i dont spend most of my days plowing my own ground too ok, my stomach is growling right now lol, i understand ok.
"Let them," and see what happens imo. Ones whole life will change overnight. Bc ppl are not going to change, in this context. Ever. There are none...in that context. Wadr you are just begging for future repeated blows on the head, i guarantee you someone will be disappointing you today, and every other day, you will be in hell, are even, right now, imo.
