who are friends?

• http://www.youtube.com/watch?v=wZHmsVRshwU&feature=fvwThis question may be simple to answer.when ever the word friend come's in mind we associate it with a person whom we find interesting and someone with similar ideologies. friend is just not the one who laughs at every joke we crack but the one who makes us smile when we are in deep sorrow,the one soothes us,loves us and as a whole is a part of ourself..... its hard to find a good friend,but once u have made someone keep it throughout lifetime,they r the jewels of our lives ......... :)
