Speaking from my past experience, it is very difficult to find good friends that you can trust but once you have found them, they are worth keeping forever! Therefore, I think friendship is the most important relationship that anybody could have. The qualities I look for in a friend are a good sense of humor but sensitivity when it matters. Also that friend would have to be strong-minded and highly spirited. I think that these qualities are the key qualities to look for in a good friend. Even the strongest friends can still have arguments, although usually about more serious topics, rather than the usual teenage childish arguments. Some matters can seriously affect a friendship. If one of your friends started experimenting with harmful and dangerous drugs, what would you do ? A good friend would try to help as much as possible, whereas a bad example of a friend would simply shrug  and turn a blind eye. Not only the bad things affect friendship ---- good activities do too. Such as bonding with one another, not just by going out on a night with them but by spending quality time with them and talking to each other, which indicates a good ability to communicate. This is a key aspect of a good friendship. Good friends do not always have to be in the same age group as you. I have a good friend and she is 47 years old and I am 16. Unfortunately, some people lose contact with their friends as they grow older, which is a sad way to lose a good friend. I think friendship is one of the most important things in life because if you have no friends you will have no happiness. According to the author, which matters least in friendship?
Age. Sensitivity. Sense of humor. Communication ability.
