I see “trust” as a neutral and neither positive or negative. Meaning that, I trust someone will act a certain way or say a certain thing based on the nature of our relationship and their track record. Those actions or words can be either positive or negative.
For example…
I trust that my wife always has my best interest at heart.
I trust that my nephew, shortly after breaking up with current girlfriend, will come looking for a handout or help with his children and act like nothing ever happened (despite him being a volatile, selfish, asshole a mere 6 to 18 months previous).
I trust that my friend will, at least once, in any lengthy get together bring up to all our struggling friends with children (us included) how great it is that she and husband will be retiring early and have oodles in the bank thanks to not having kids (and a timely inheritance from her mother).
I trust that every morning, around 6AM, a cold, wet dog nose will find its way into my face as if to say, “Wake Up!!”
I trust that my daughter, despite being smart, articulate, and generally caring will not take care of me in my old age, because she has said so multiple times.
