I went through several hours of training to work as an aid in a nursing home when I was 16. (What was I thinking?) The training was fine, I passed, I went out on the floor.
One 1/2 shift later and I was done. Because, ewww. I can't handle the elderly. Sorry, but it's true.
I will always remember what the woman over the position told me. Some people can work with old people, some people can work with babies.
So, babies. I am all about babies.
