"Old Saying Tells to Not be Gullible" by Susan Pearl

"They swallowed it, hook, line and sinker".

Being naïve and trusting are really not bad traits but the problem that these traits can make a person vulnerable to be taken advantage of by others.

We have to stick with the facts and the facts are that not all people are nice and some of them are looking for susceptible people to believe the lies they are telling.  No matter how they look, as they can look the part of being genuine and sincere, no matter what they say, as they have been skilled for buzz words that they notice show an inroad for more conversation, no matter how coincidental as it may seem (for instance you are in recent need of what they have or a service they can provide)---REMEMBER a stranger is a stranger and don't ever forget it.
Be aware and keep evaluating and don't be gullible---don't swallow it hook, line and sinker because then you will be caught by them and that is exactly what they wanted to do (to hook you).  Don't be gullible.  There "are" coincidences in that strangers can come along right when we need what they have to offer but verify authenticity and find and cross check references before taking any action that can set you and your family up for problems or harm...…. beware and be aware in not taking their bait.
