My father-in-law sent me a link to a flash mob singing the Hallelujah Chorus in Macy's recently and I loved it. It gave me chills and I wished the could have been there!
Then I noticed a "related" link to another flash mob in Belgium and I watched it and laughed so hard because it is adorable. Maybe that is the key to not taking life so seriously!? Just break out in singing and dance whenever you feel like it!
