Pearl is a rescue goat at The Gentle Barn in Tennessee. Apparently, Pearl is in love with their UPS man. She will drop whatever she's doing when she hears his truck. Of course, he brings her peanut butter treats and gives her love while he's there... so why WOULDN'T he be her favorite?! :)
Apparently the feeling is mutual because the driver says when he sees Pearl run to greet him, "everything is better."
