So many of us bottle up thoughts and emotions that need to be communicated.  Mind you though, have it come from a good place, not a resentful or judgmental one.  We are all human, and while we cannot predict how someone will react, if you go into discussion with true sincerity, non-judgement, an open mind and an understanding there are two sides to every story, you should be off to a good start.

Avoid building up layers of stress in your life for things that may be cleared up through communication. Preferably with face to face dialogue rather than texting :).
