Shirley and Tarra's relationship is ever-evolving. Tarra has matured much over the past year, moving out of her "little sister" role, and Shirley has opened up more emotionally, not always needing to be the "strong one" anymore. This growth has made Shirley much softer, but it has not taken anything away from her silly, playful side. Along with sharing stalls inside, spending time in the habitat together, and eating together, this bonded pair still also play together. This one morning, Shirley and Tarra were extra silly and started playing as soon as they got out of the barn--Shirley showing Tarra that even though she has almost 30 years on her, she can keep up, no problem.
