I do not know much about my sister-in-law's job except that she teaches history in a public high school. Usually a high school teacher teaches several different grades, like 9th, 10th and 11th.
Correction: Their daughter attends a public high school, not a private school.
My brother and his wife (my sister-in-law) both do NOT have to work extra jobs to send their oldest daughter to college because they can afford it. I was saying that she works as a waitress just for the summer only when the school is closed. She doesn't get paid when she is not teaching for the summer. Am I right, Shel? Again, I do not know much about my sister-in-law's job. I asked my sister about this and she said she doesn't know much about her job, either.
