Most of us get deceived by false people pretending to be our friends. What to do if this occurs again? Just see who is lying, cheating, or who is honest, truthful. I know this is the most difficult, but we need to test them. I don’t think that some bad people really change, because they stay the same. It goes day-by-day to see if this person is hiding something under his/her sleeve. Check if someone has pulled their tricks in their mind box. One way to see is when they use their malicious laughs, and stand in a jerk position. Check on your friends to see who is loyal to you. See if you’ve caught them in a lie when they are lying to you, by watching their face. If s/he isn’t to be trusted give them the silent treatment and walk away from their lives. Be careful of mean people trying to ruin their lives, because they’ll be caught their lives in jeopardy deservedly so. Hang out with people who care about you and are your real friends. Our experiences in life should know whom to trust the most.
