This frog of llittle brain can only think of a family story about trust. It involves a relative, an aligator and a stream.

It doesn't have a happy ending for my relative so I will not repeat it here.
Trusting things is much easier than trusting people. Trusting in others is difficult and often ends in failure. I found this quote that may explain it much better than I can.
"You may be deceived if you trust too much, but you will live in torment unless you trust enough." ~Frank Crane
There just is no quick, easy answer so this frog of little brain is of no help at all.
