New vocabulary word invented by Taegan

We went to stake conference last weekend.  Our kids did pretty well, but Taegan couldn't last through the last two speakers, so Paul took her out.  At dinner, I asked Paul if he was able to hear our Stake President's talk because I thought that it was really good.  He said that he had taken Taegan to a room where he could hear it over the speakers.  Then he proceeded to ask the kids what they thought of President Cheney's talk.  Well, when it got to Taegan's turn, she said she didn't listen because she was "stilling."  We had no idea what she said and kept asking her to repeat it.  Finally she said, "I was doing this."  Then she sat up tall and folded her arms in the chair and was quiet.  We then understood that she meant that she was focusing on sitting still, so she didn't listen to the talk.
