Trust is a tricky one for me. Is it that T's are trustworthy, or does it come from our ability to trust?

Also does trust have to be absolute or graded / boundaried? Like I trust my local shops to sell me healthy food, my bank to look after my money, my dentist my teeth.

I trust my T to treat me with respect, to maintain their professionalism, to be honest with me. But can I trust T to always be there? No that is beyond my control and also T's.
