Yeah, I think, I put a clip on here about a man, a local of mine, who lost his eyes and hands due to a mine explosion over in Iraq. A house was made special for him. He even has a voice regulated Toto.
I don't have sound on my laptop but, I was able to watch the clip you presented. He seems very happy and well-adjusted, but, trust me on this one, he has his bad days just like the rest of us. When he asks why, and feels angry and bitter, and even jealous of those who are whole. It is okay to feel that way.
Sometimes, you can see the person's problems, and other times you can't. That is why, no one should judge another human being, without having walked in their shoes. I am reminded of the parable, about a man complaining about not having shoes until, he met a man who had no feet. But, still, when you really think about things, and people's problems, it doesn't make it any better. You can be grateful for that moment, but, like in my case, I have blood vessels in my brain that are inoperable, that might bleed out, I have a hard time using my right arm, and, the pathology reports state I have pulmonary lymphoma. Those things you can't see, I can look in the mirror and I look pretty damn good. But, inside, it is a different story. That is why people got to be gentle when someone says, they have a disability but, look like the picture of health.
Everyone has a story to tell, everyone has problems, and I wish for a kinder society and people. That is my wish.
