In order to start becoming a good friend with someone, and therefore expecting that person to become a good friend, you need to be a good friend yourself. Reflect on your own personality and determine what your strengths and weaknesses are in being a friend. Create a goal to improve one of your friendship weaknesses to help you become a better friend. For example, maybe you sometimes forget to respond to your friends' text messages, so you could make a goal to respond within a few hours every time. You would not like it if you found out that your friend's true personality is completely different from what you thought it was. Therefore, you should be yourself around your friend.  Show your quirky habits. Maybe they do the same things! Share your sense of humor and tell jokes that you think are funny. Share your hobbies and interests, even if others think they are “weird.” Your friend might be interested in them, too! It is important to not try to force your friend to be someone that he/she is not. Your friend is a unique person, and just as you want to be accepted for who you are, so does your friend. There is a wide variety of things that you can do with friends. Invite your friend to hang out with you so that you can build up your friendship.  Go to the movies Go to an arcade Go shopping Invite your friend over for dinner Invite your friend to play at your house Invite your friend over to play board or video games Join in a neighborhood game, like soccer or basketball When it is your friend's birthday, be sure to give him/her a card or even a small gift. They will also appreciate if you acknowledge when they do really well at something, when they win something, and when they get accepted into a group or program.  Be sure to show genuine excitement for your friend. He/She will likely be able to tell if you are not sincerely happy for him/her, which will damage the friendship. If you also made an attempt at the same thing (for example, you also applied to get into a certain program) but did not succeed, avoid...
