If I caught Chelsea doing something, like ripping up a newspaper, or other thing she shouldn't have been into, I NEVER raised my voice, quite the opposite. I'd stand, clear my throat (and did that get her attention!), and ask in a quiet voice, 'What was this for?'
Chelsea's head would drop, and then came the 'Oh No, I've been caught' look.
I suspect, that at one point in her life before me, Chelsea had been punished with newspaper. Whenever I lit the fire, and crumpled paper up to light, she would come over and sit by my left side, with her head down. It tore me up to see it, but she did it for her entire life.
April, on the other hand, hears me crumpling paper, comes on the tear, ready to tear. She has a riot with it. Christmas morning, with all the wrapping paper, she's in her happy place.
April doesn't seem to make a connection between right and wrong. She rarely gets into stuff she shouldn't, but nothing that I've found seems to make an impact on her. Just goes on happily through life.
