When did manners and courtesy disappear?

Was it with woman’s lib? Meaning men no longer give up their seat for a woman wearing heels?

Why don’t people say ‘excuse me’ anymore and instead stare at the back of your head expecting you to know they want to move instinctively?

Why is it that an train aisle full of standing people doesn’t inspire someone to move their handbag and feet off the seat next to them?

When did a queue become just a way of standing before turning into an all out bun fight to get through a door?

Why did I have to ask to sit down, when I was on crutches?

Why, when paying for an item, does the next person feel compelled to stand so close to you, you can feel their breath?

In a world where personal space is becoming more and more precious, I say we need, more than ever to regain some of the basic manners and courtesy with which we are furnished as children. Of course, in saying this I am assuming that manners are actually taught to everyone. Based on the evidence from public transport, public events and your average shopping centre, I reckon it’s a subject that needs to be put on the school curriculum.
