The world is full of people that never stop talking, it expects us to be the talker, the show maker, the entertainer, anything that fulfills this peaceful place with sound of our larynx. It's nice to have someone sitting back to back with and let the silence talking instead. While the world always disdains it as trait of submission, even the lack of confidence to shout out what is on your mind. Shame on them they can never see it like we see. Silence is the strongest voiceless statement that could convey what is in your heart to those who are dear to you, not what we are constrained to say, but merely the message: i am always here for you even you are way too fatigued to make a single sound.
