How are you doing in your response to those who speak truth to you in love?

I think this is a tough one for me. I often times have a hard time speaking the truth. What I mean by that is that I often will hold my tongue as a means to avoid confrontation. There are times when I want to say something, yet I hold in for the sake of avoiding an argument. The issue with that is that it can often turn into a passive-aggressive situation, where the frustration I might be holding by not saying anything appears in another situation, or in my disposition or attitude. Sometimes holding your tongue is not the best thing to do. Sometimes you have to say how you feel, truthfully, but not with ill intentions.
