Veronica, thanks for teaching your students these sorts of things. I used to work in our public community college, and I was appalled at the inability of most of the students to write a complete sentence. These days, one of my friends teaches English at a for-profit technical school; we can all tell when she's been grading papers from her foul mood. She says most of her students are functionally illiterate, despite having a GED or high school diploma.
