Hi Jason, very nice and deep post.
"Grief/sorrow and joy/fulfillment/happiness are two sides of the same coin and can never be separate." - If you feel that way, you should definitely try the Argentinian Tango! I'm dancing it for two years now and what I can tell you is that people who seem a bit sad (and sadness usually brings a unique calmness with it) are able to connect much better with their partners and are usually much more pleasant to dance with. : )
That sounds incredible, the Argentinian Tango! :) that is beautiful... i love witnessing dancers express their emotion through movement. :)
