interview at childrens hospital

Sunday afternoon I went to children's hospital to interview to volunteer at children's. When I got there I was a little nervous. But what I didn't know is I was already accepted to volunteer there, they just wanted to go over the plan, the overview of volunteering at children's. So I am starting to volunteer in a couple weeks, I just have to go to an orientation and go get checked by a nurse to make sure the ill kids won't get sick.
