Back when I had a VCR/DVD combo, Precious had perfected the "If I push this button she reacts" move. Depending on whether or not I was trying to watch something it was either "Don't do that!" or "Oh, aren't you clever!" as she would start a tape playing. Alas, that machine has been replaced and all those VHS tapes are now useless. Precious has replaced playing tapes with sitting on top of the DVD player.
