Study the following paragraph and decide how many run-on sentences are involved. "My worst experience of the week was going home for lunch, rather than eating at work. My children didn't know I was coming, they had used most of the bread. All I had to make a sandwich with were two thin, crumpled pieces of crust. I sat there eating my tattered sandwich and trying to relax, then the telephone rang. It was for my daughter, who was in the bathroom, she called down to me that I should get the person's name and number."
