So many of us accept friend requests or have virtual conversations with people we instinctively don't like...for no other reason than we don't want to hurt their feelings. Setting boundaries means saying yes to some things and no to others. When we say yes to someone we really don't want to, we are actually not be truthful with ourselves or them. We need to say no without an explanation or an apology and understand that when people get mad at us for saying no, that that's ok. And a great sign that you really don't want them in your life.
