A bad friend will only want to hang out with you when they feel like as their only intention is to use you for their own fulfillment. They will always wander everywhere in school or at home or place of work spilling all your secrets. A bad friend will spread your business to everyone with the intention of make people think they are better than you are.
Others because of jealousy will do this with the intention to hurt you or someone else.
For example, if you win a lottery, a bad friend will make sure you have spent the money to the last dime without giving you advice on how to invest.
They will only be there in good times but run away from you when you need them.
The definition of a friend, and friendship, is based upon one's own notions.
Many people look for different characteristics in friends, things that may be common in nature.
The insight to this person's life, is merely an observation from a person's perception.
Usually, these are the types of friends that a person may meet in school, at work, local hang outs, or somewhere that is frequented often.
This is because a friend needs to be someone you can always count on or rely on in times of trouble just like they would rely on you if faced with the same situation.
Many definitions of a good friend agree that he or she should be some that are attached by your feelings of affection and personal respect.
