And you know, while reading your article I couldn't but murmur a song from a soviet animation “Baby-raccoon”: “Because of a smile it'll be lighter, because of a smile a rainbow will wake up in the sky, share your smile and it'll return to you” (hope my loose translation doesn't irritate you))) Yep, this song always makes me smile)))))
