1. accept your friends for who they are, dont discriminate against race, religion OR sexuality.
2. Stand up for them, no matter what there will always be bad friends and bullies so everyone needs someone to help in those situations.
3. Cheer them up, remember everyone needs a hug sometimes no matter the problem, be it family issues or just failing an exam, friends are there to keep you happy.
4. Muck around, don't ever be too serious, friends are totally free round each other, nothing can embarass you when your just with your friends.
5.Don't be a total pushover, being too good a friend and doing whatever they want is never good, if you don't agree just say it, if they were a good friend they would understand.
6. Never forget them, no matter what remember your friends, no matter the distance between you try to talk as often as possible.
7. Just be yourself, if they don't like you for who you are they're not a good friend and not even worth changing for!
