What's with all the hay?

TW was back at work today or training as she called it. Bracky said that means sitting round with a load of nobbers being nobby. I think that's rude though. In the morning , TW appeared and gave us a big huge bag of timmy hay to share. Yum. Later on ZM appeared and gave us a bit more hay and fiddled with the fence and made another bit sappy. That's not nice. At tea time TW came back, we were so happy we cantered around the track to see her. She gave us a bowl of grub and another bag of hay.but this time she scattered the hay all akut so we had to walk around for it. I don't understand so much why she feeds us all this timmy hay when there's loads of grass . Bracky sAYs ITs cos sheS a bleddy control freak and maybe she should control her own eating. Frank just laughed and says he likes timmy hay and loves TW lots. I don't mind, it's all good here. Just confusing.
