A smile.
HEY! I didn't say "nothing but a smile." Get your mind back out of the gutter.
Shalom.
Fifteen days ago, I read that smoking can kill you, so the next day I stopped smoking. Twelve days ago, I read that too much red meat can kill you, so the next day I stopped eating red meat. Eight days ago, I read that drinking can kill you, so the next day I stopped drinking. Three days ago, I heard that cell phone can kill you, so I stopped using my cell phone. Yesterday, I read that having sex can kill you, so this morning I stopped reading.
