sometimes feelings are subtle. Just begin to think about .. what did i feel about that. Then say it. Don't worry about outward manifestiations in extremes.. If you never have showed emotion it likely wont start like that. It might be just a small watering of your eyes, or tension, or nervousness, its all telling you something. its your emotion inside. As you begin to open up.. so will your emotions. Believe me.. I think its starting to happen to me.
