I miss my horses too, I had some amazing ones. Life circumstances took me away from my little place in Idaho, I sold all my horses, I was without them for about 8 years, we just got a TB broodmare 2 years ago, she's due to foal this spring. She's not the same as the horses I had before, she's dingy, doesn't know where her feet are, as far as I can tell there's nothing wrong with her eyesight. She came off the track, I'm assuming she was raised in perfectly flat paddocks and stall kept.
That's wonderful you chose to take care of your mother, family is darn special. My mom and I lived on opposite coasts, I hadn't seen her in 5 years, then she retired and moved about 25 minutes away from me, it's be great to be able to see her regularly again.
