It's only fair to warn you that if you watch this video, you are liable to have a cuteness conniption fit. And if you show it to your kids, they are likely to beg you for a trip to the Elephant Sanctuary in Tennessee.
That's where Tarra the elephant lives. Recently her best friend Bella suffered a debilitating spinal cord injury. Rather than roaming on the nearly 3,000-acre sanctuary, Tarra stood vigil for three full weeks outside the sanctuary office, where Bella was recuperating. This loyalty is not uncommon in elephants, who typically form lifelong friendships--except that Bella is not an elephant herself. She's a stray dog who lives on the sanctuary.
Perhaps thanks in large part to Tarra's support, Bella is now all healed and once again frolicking alongside her elephant friend and letting Tarra rub her belly with her giant foot.
