I can care for family/friends, but not strangers as a career. Like you, I would help the old man, but I wouldn't want to be a caretaker as a profession.
It's my grandpa. He's still got it, but it's sort of in remission. He's in his late 80's and could only handle one dose of Chemo(I think that's spelled right).
But I also take care of his wife, my grandma, as she has the beginnings of Alzheimer's.
To make your heart heavier, I also take care of my mom. She also has a broken foot and I have been helping her by cooking and cleaning. I also try to make them all laugh when I can.
Thanks for the kind words Smerkin. I bet you're like me and do it simply because it's right and/or we love them.
But don't let this all fool you into thinking I'm not a dick sometimes. If I'm crossed I tend to be a dick. X{D
