blind leading the blind

We made a train leading to the therapy gym. In front was Mrs. C in her wheelchair, I was pushing her, followed by her son who held onto the walker I held out behind me as a guide for him. Mrs. C is 84 and was admitted for a COPD exacerbation. Today our treatment focused on training her son to be her 24 hr caregiver/supervisor. She needs help to stand, walk, and transfer and will be returning home on oxygen. Her son is blind. I didn't ask how he began blind as I wasn't there to begin treating him too and I knew that asking probing questions would inevitably lead to that. Again, my purpose today was to train her son how to safely assist Mrs. C from the wheelchair to the commode over the toilet. He passed the test, even when I tripped her to see how he'd react to a near fall. He'll be back Monday and all of next week to continue training. Amazing to imagine what some people are dealing with out there! But somehow they survive and hopefully this pair of blind leading the blind- will make it happen.
