You can make friendship with people in different ways.It can be a friend from school,a friend who is your neighbour,or a penpal friend.In my opinion the main thing about friendship is trust,when you can talk about everything with a person,and you know this person will never betray you.Also one of the important things is good sence of humor,when you are positive,it can attract a lot of people.There are no rules how to make friends,but the main thing is that you have to value this friendship and you have to be responsible for that.When your friend is poring out his heart to you,you must listen and if it's in your forces you have to help him.
