Do it again Daddy!

We have controls on our steering wheel in our vehicle. As we were going to church, my husband turned down the radio by the controls on the steering wheel. My daughter couldn't figure out how he did it. She asked, "hey how did you turn down the radio?" Doug said it was magic, watch. He literally moved his hand up and down as he is turning the volume up and down by the controls on the steering wheel. "AWESOME!" Katie exclaimed. Well, she decides to try it from the back seat. Of course, whatever sissy does brother has to try. Get a visual here. Both children are waving their hands up and down trying to get that crazy radio to turn the volume up and down. They were so puzzled because it wouldn't work. Katie asked Doug, "why can't I do it?" He told her that it's because she wasn't in the front seat. When we stopped, she unbuckled, leaned up and waved her arms. Doug told her to turn it up. As she moved her arm up, the volume went up. She was amazed. Colton had to have his turn. Both children just cackled and chuckled. What can I say? We are easily amused people. It doesn't take much to excite us. LOL!
