NOT A TEACHER
DEAR FELLOW MEMBER OPHIUCHUS:
(1) I believe that your second interpretation is 100% correct.
(a) In other words, you draw a line that you will not cross.
(i) Here is a true example. It concerns a very sensitive and
delicate subject. I will be super careful with my words.
A few months ago, the people in a certain country protested
in the streets. The president told the army to use guns to
stop the protesters. The generals replied, "We will try to
ask the protesters to go home, but we draw the line at shooting
our fellow citizens." So today that president has "retired."
