Rudeness

I thought i'd discuss rudeness as it is one thing that really gets on my nerves and i do think is bad. I'm bringing this subject up because week after week the lectures are disrupted by people walking in and out during the lecture...what you all got such infantile bladders that you can't last an hour until the break!! Then there is mobiles going off and people talking so loud it is hard to hear what's going on... it is inconsiderate and down right rude!!

If people don't enjoy the lesson and don't want to be there DONT be there and give us all a break. I really can't understand why people come to a lecture and then talk all the way through it, if it is so boring then go and do something else, that way the ones who are interested, or at the very least have the manners to sit quiet and not disrupt the lesson for others, can enjoy the lecture in peace.

Sorry but i had to get that off my chest.

Here's some sites on rudeness and etiquette:
