Trust is very much like Respect.
It is something that must be “earned” over time.
We have to be “given something” to believe or not to believe.
Only after observing the honesty and integrity of an individual should we allow ourselves to Trust.
To trust someone is to believe what they tell you is the truth and they care enough about you not to betray you.
You sense you can confide in them.
Having said that I realize it’s not uncommon to hear folks say, “I’ll trust anyone until they prove me wrong.” People who think this way are a dream come true for any con man!
