Every day, every one of us have occurrences or situations which happen to us.
We enjoy sharing special, interesting, or funny moments with others. We do so that we may relive that moment and have another virtually experience that time with us. We also share emotional or stressful situations in order to purge ourselves of thoughts and feelings, and to receive empathy in order to deal with them.
Many of us use the internet, specifically AN.com, to share and/or deal with those thoughts and feelings.
Art is another method that can be utilized in a similar fashion- a thought or a feeling can be made tangible and put outside of our head, onto some media for study and consideration.
