Around 10:30 a.m. I went with my BIL and MIL to the hospital. We thought she had suffered a stroke. She had but it was mercifully very mild. She has some slight slurring of her speech and some weakness on one side of her face but no blindness, paralysis, or big muscle weakness. She's mentally intact. They are keeping her overnight to make sure nothing else goes wrong and so they can do some tests on her carotid arteries. Considering the situation, she's very, very fortunate.
But she is 91 so please keep her in yours prayers. :)
