These characteristics, however, may not be at all important to someone else. For example, if a person's priority in life was to go out every night, get drunk and get up to random mischief then they are more likely to think it is important that their friends are outgoing, loud, mischievous, playful and exciting. On the other hand if someone were timid they would be more likely to want a friend to be more approachable and kind-hearted.
No matter what your personality, certain characteristics should always really be pretty high on the list of characteristics of a friend. Things like trust and loyalty are pretty much essential, because if you can't trust a friend and they are not loyal towards you, are they really a friend at all? If you know that a friend would talk about you behind your back then, no matter how much fun they are, they should never really be considered a good friend. What makes a good friend is always up to the individual, but it's always best to make considered and informed choices.
It can often take a few years before people consider someone a good friend, as it is difficult to really get to know someone in a short length of time. People who you have known for a longer time will also have more understanding about what make you, you. For example, things you have been through in the past and life experiences.
