I believe that watching is not bad if there is a person’s suspicion of any dishonest deeds. I had to cooperate with detectives https://truthprivateinvestigators.com.au/contact/private-investigators-adelaide/ about a person whom I trusted and this person turned out to be completely unfamiliar to me. So since then, I do not think this is something bad. If there is suspicion, then there is a reason.
If you go looking for something...you will certainly find something! No thank you; I've never been and will never be a snooper. What is done in the dark will always come to light...that is enough for me! Besides if you stop ignoring your intuition...you won't have to snoop. ~My Two Cents :-)
