That is exactly like Baby Girl! She's the leader of the herd as well, though she seems more fit for the job. It's funny to watch her lead the great exodus from the high pasture down to barn for hay. I always imagine dramatic music playing when she appears over the hill.
As far as sweetness, she is famously sweet -- it's what everyone remembers her by. Loves people. Licks on me constantly, puts her nose to my face and gives me a good whiff of horsie breath, loves on the kids that come visit the barn... She isn't too keen on strangers riding her, but petting and giving treats is perfectly okay.
