ShyRea Harrell, left, asks Andrew Moffitt a question about Sprite, his 5-year-old alpaca, on Wednesday, April 12, 2017, at Magic Valley Rehabilitation Services in Twin Falls Idaho. For Moffitt's senior project, he got Sprite certified as a therapy animal. NOTE: It's an alpaca inside a building. As soon as I heard about this assignment, I knew I wanted it. It was funny, weird, heartwarming and interesting all at the same time.
