Suspicion is good, but there is a certain kind of suspicion that makes everything work wonders
Suspicion many times leave us with the wrong conclusions. Why is this? because we have made up our mind as to what the conclusion will be hence (no longer call suspicion but opinion). Both the right and the wrong suspicion can get you to the same answers sometimes. The only issue is that the wrong suspicion makes you feel like you are right and causes you to believe that way of suspicion - thus going forward giving you wrong conclusions [and one unable to understand why the mistake occur]
This is called; "I got it dead right the first time"
We are all suspect in someones eye. But the right suspicion tells you who someone is.
