The lady can whistle

Penny woke up one day last week and started whistling while we were walking down the stairs. I couldn't believe it. Ryan thought it was me whistling on my way down the stairs. So I spent the next few days trying to get it on video. The video below is our best attempt at capturing it. The quality isn't great cause it was on our tiny camera that doesn't have great sound. But it's the best since I don't whistle in this one at all, any whistling you hear is coming from the lady.
