Correction ... in these days of Political Correctness, we are all created equal and therefore the niceties I am accustomed to (such as opening doors, or keeping them open for other people, giving up a seat to someone who might benefit from it more) seem to no longer apply to the world. I shall continue to observe them, whatever the sex, etc.
p.s. Got 10/10 today, but took twice the time to read the questions.
