Background: You have just received a letter from your Great-Aunt Gladys, who lives in
Cracker’s Neck, Virginia. She is a sweet old lady and has heard “such wonderful things” about
you. Aunt Gladys never made it past the eight grade, but she has an insatiable curiosity. She is
somehow under the impression, bless her misguided heart, that because you are taking chemistry
this year, you know the answers to just about all of life’s mysteries! Here is the end of her last

       Anyway, honey, I do hope things are well with you. I’ve heard such wonderful
       things about you… Which reminds me! Your cousin and I were sitting out on
       the back porch last Tuesday, just like regular, and I got to thinking about some-
       thing that has been bothering me (besides my rheumatism). What I would like
       to know is (insert your question here). Now, remember, I’m getting along in
       years and I ain’t had the wonderful education that you’re getting there at Mercy
       High School. So when you write back, you be sure to explain it real good and
       simple so that us regular folks can understand.
                                              Love to the Family,
