A memory from the first day of sixth grade chorus class: Mrs. B. welcomed us to her class and said, "Go ahead and sit anywhere..." Some of us climbed the riser steps and started to sit down in the back row, when she clarified, in her Texas accent, "...but not back there! I need my bifocals to see back there!"
Just as being invited to "make yourself at home" doesn't mean you should start eating food out of your host's refrigerator, some of us learned that day that the word "anywhere" shouldn't always be taken literally.
