i had a mentally challenged individual look at me the other day and their face lit up as they told me "ooh, you're happy" as if surprised to see someone in that frame of mind, given the cirucumstances; however, it made me think of how we "light" each other with just a smile, a glimpse, a wink, a kind word and i have bought several of these to pass on for folks to thnik of the positivity in life and "light" each other up...so keep them coming...
