Etiquettes

Its not so interesting topic to write about, but just giving it a try- as I have learnt etiquettes by experience and not in the books. There are so many etiquettes- email, business, eating etc etc. You come across people who do not have good etiquettes, who don't have any etiquettes (who do not know what does that mean) and some people are just so full of etiquettes. 
And some are absolutely funny people whom we all happen to meet- who don't have any etiquettes but talk about etiquettes about others :).
I learnt that it is important to have a crisp and clear communication while @ work. Important to have respect and manners to misbehave/ behave while you are with your friends and partners. 
I find my this post to be a little boring one as it is not of my taste either, but I met a person today who doesn't have any etiquettes and was commenting about everyone else's!
