If a troublemaker tries to re enter your life, think twice before you respond or let them back in. Forgiving and remembering good times are well and good but you run the risk of them causing havoc in your world again. You can tell yourself that whatever happened is in the past and they are probably a different person. Or if you know of something in their life that hasn’t gone right, you may think they need a friend. But ask why they want to know you again. Not everyone who wants to come back has good intentions. And if your gut tells you they have an ulterior motive or it would be more of the same from last time, go with that feeling.
