Etiquette

In order to present a good impression to others, you need to act like you weren't raised in a barn! It is very difficult to deal with people that have no manners or have no concern for others.

Common Sense Stuff:
~Choose your words wisely and don't rush to comment about things you don't know much about.
~Being a good listener is often better than speaking.

~You don't need to have an opinion on everything.
~Think things out before you speak, especially if you are a person who may be poor at finding the right words to say.
~Speak with respect for others.
~You can do this by avoiding negative remarks that may insult someone else.

~Do not use expressions or theoretical examples that imply disrespect or degradation or that invite people to imagine offensive scenarios, such as "what is up your butt?" or "how would you feel if someone..." followed by a description of violent or degrading acts. You may not intend this as offensive, but it is.
~Always respect older people, and listen to them and learn.

Using the terms "Thank You," and "You are Welcome" shows that you have manners.

~Hold open a door for anyone following you closely.

This is a sign of good manners and has never changed. There are no strict gender rules in this day and age.
~Speak highly of your parents, even if there are things about them that you do not like.

If you cannot do that, stay away from speaking about them at all around others. It looks tacky to insult or speak badly of the people who brought you into this world or raised you.

+ Don't air dirty laundry about your family. It's tacky and rude.
+ Try not to swear or use curse words so much.

Profanity is a sign of an unchallenged mind.

+Try to show that you are more interested in the person you are speaking to by asking them questions about themselves.

*Don't steal their spotlight by just talking about yourself. You don't want to come off as selfish.
*Pay attention to how you carry yourself. In other words, act like you have some class, which goes hand in hand with manners.

*Don't slouch, have a neat appearance, shake hands, be clean, hold your head high.

*Don't put other people down, belittle them or spread gossip.

*Never openly criticize someone in an attempt to put them down or to make yourself look better.

*Be complimentary and positive.

Having an opinion is one thing, but being insulting is a sign of bad manners. it is never polite to tell secrets in front of someone. If someone else is gossiping or belittling them, show you understand in a neutral way (a small nod to show you comprehend or an "mmhmm" should do) and then go on to compliment them on something as closely related as possible.
Don't interrupt another person who is speaking, regardless of even if it is a casual conversation.
Try to let them finish what they are saying; in other words, listen.
Get off the phone before entering a restroom.

No one cares to hear you doing your business.
