What does etiquette and manners mean?
Etiquette is a code of conduct that describe the expectations for interpersonal behavior based on current conventional norms in a society. Basically – its the way we are supposed to act when we are around other people, especially your elders, teachers, and authority.
Manners are the unenforced standards of conduct which demonstrate that an individual is proper, polite, and refined. Manners is treating others how you want to be treated.
Even kids like YOU, can learn how to be polite and proper.
Here are few of the etiquette and manners kids should be aware of.
Don't go looking through other person's personal or private belongings without his or her permission including their diaries or love letters. This is a breach of privacy. We need to respect other peoples private space, even your brother or sisters and especially your moms and dads. Privacy is a basic human right. We need our privacy to become the best we can be. Somethings just aren't meant to be shared, read, seen, etc. Setting boundaries for your own privacy needs is important as well.
Family matters should be kept private and it is not nice to share it with others. What goes on in your own family shouldn't be shared with everyone on the block. HOWEVER, if you are being hurt, neglected or abused in any way, you need to tell someone in authority, a teacher, counselor, police officer. TELL SOMEONE!
Remember to knock and wait for the permission to enter when the door is closed
Your room and other personal things like towel are your responsibility. Do not expect others to clean it up for you. When you keep things put away then you can easily find them when you need them again. Letting dirty clothes and dishes pile up, invites bugs – keep a clean and tidy room at all times and you will have more time to play.

Always use the proper table manners like washing your hands before eating, don't stretch across the table, ask someone to pass what you need, don't talk when your mouth is full etc.

Don't make others feel embarrassed, always think how you would feel if you're in the same situation. It is also wrong to bully anyone.
Ask for permission anytime you need to borrow something and ensure you return it in same condition.

As courtesy to others, it is not good to eat on public transportation.
While in a public transport, always offer your seat to old people, pregnant women and handicapped person.

Allow people to exit the elevator first before entering.

Always put your trash into the garbage bin.

Turn your portable MP3 player or iPod's volume down so that other people won't hear the scratchy sound of your earphone.

Open the door for adults and make them pass through first.
Being polite will earn you respect and trust. These are valuable characteristics to a successful life.
