Qualities & Characteristics Of Being A Good Friend

Be What You Are

In order to be accepted by others around you, do not try to be somebody that you are not. Be yourself. Let yourself be known and

accepted for your own merits, rather than for being somebody that you are not.

Be Honest

A dishonest person may have friends around him/her, but not the true ones. If you to want to be a good friend to others, it is very

important to show loyalty to the people around you. Do not break the promises that you have made to them. Think twice before

giving your word - whether you can stand up to your saying or not. In case if you have promised and could not fulfill it, be honest to

tell them about the whole dilemma.

Be Dependable

You should win confidence of people to whom you want to be a good friend. This is possible only when you show honesty to them.

Be loyal. If your friend shares his/her best kept secret with you, do not let any third person get even a small hint about it. Blabbing

the secret to others would result in the friend loosing confidence and trust in you. You will be then considered as a backstabber.

Remember, trust is the foundation of good friendship. So, do not let loose their trust on you, at any cost.

Listen

Listen to your friends. Lend an ear to their needs, emotions, feelings and desires. Do not limit yourself by just listening to them.

Show your reaction to whatever they say, with gestures. Showing sympathy won't serve the purpose. Try to empathize their

situations.

Be Present During Crisis

want to be a good friend, is the need of space in friendship. While getting personal with your friend, do not forget to leave a spacefor him/her. It is very important to maintain individuality in friendship. Do not be clingy or needy. Give your friend enough time to
