Dummies guide to elevators

I don't know what it is but this country has too many people who are too dumb to understand the basic common sense rules of using an elevator i.e. the lift, for those of you who are one of these dummies. Rule is, if you're waiting for the elevator and the doors finally open, you let the people inside exit FIRST FIRST FIRST before trying to squeeze/barge in. The doors are NOT going to close permanently forever and ever if you let people out first, you nut! So many times have I innocently waited for the lift to reach the ground floor, waited for the doors to open and then nearly been squashed to death by a stampede of pushing children and their parents trying to rush into the elevator as if the doors were only going to be open for 5 damn seconds. What is up with these parents? Can't they teach their kids to be a bit more civilised? But then what can I expect when they themselves seem to be lacking a certain section of their brain...hmm....
