Friendship:
Friendship is a very amazing thing! (No, <u>not everyone</u> is a fake friend now and days). Friendship is considered a necessity, as you get older you'll need friendships and not just playmates. Friends are people who care about you and share your values, they don't pressure to do things that you don't want to do. Also, friends never hurt your feeling purposely, and if they do accidentally they'll be ready to forgive and move on. Good friendships don't come easy though; so if you have a friend and there is a strain between you, try to work it out. Spend some time with them and get to know them more. Don't just call them off, you may start to loose more friends. Friendship is not to be taken for granted because you can loose it easily!
