what is the real mean of being friend?

Friend is someone who you can trust. When you are sad, you can share your sadness with him/her, so he/she can give you advise or support you. A friend who also would share your happiness. When you are in need of friend to talk to, he/she will be there for you. A friendship is mutual. Both person can share a good memory, and always be there for each other in their whole life.

i think friends are that they can share emotion, and don't have to disguise

I would like to remind you of the age-old proverb; a friend in need is a friend indeed. This means that a friend is such a person whom you can trust and who will always be by your side, be it in your happiness or in your difficult days.
