{{{{{{{{{{{{{{{{HUG}}}}}}}}}}}}}} S to you and Tubby. Poor baby! I hope the heat helps relieve the pain. I know my old knees sure to let me know when it's about to rain! OW! it hurts. This getting old stuff ain't for sissies. I hope Tubby has an easier time of it. Gentle scritches and sweet prayers that he's feeling better soon.
