If the tennis balls don't do well, get her a nerf ball. I've used them before with better results. lad to hear she's hanging tough. Fighting cancer is no fun, even without chemo.
I got a PM from Lady Glock asking for heavy-duty prayers. She's not allowed to go into any details on GT, but she did privately. All I'm going to say is that she needs some serious prayers to resolve a situation she's dealing with. Can we send them and good thoughts up for her? Thanks
