About 23 years ago or so I took my G.E.D. test. I never graduated school. It was a class of about 10 people of all ages and we started around 9:00 am,took a lunch break then finished up around 4:00 pm. One young guy was very disruptive and the teacher threw him out. Anyway I passed with good grades and have my diploma mailed to me from Harrisburg,PA.
During family reunions, people would ask him questions and, if he didn't care to answer, he'd shrug and say "How do you expect me to know? I'm a high school drop-out."
