What is friendship..

Here is my pick on life.. This might help you better understand me.
I imagine friends as life savers.Yup i do(not e sjab kind though). i imagine myself as a person falling off a building, do this together wif me as you read on you might just be enlightened. Now imagine all the people you know are going to walk past one by one. Who will offer a hand to you who will be willing to save you?
Now here is the more interesting part.. Imagine that you are walking past who will you save? and why? tag if you need any further clarifications on my thinking..lol.
and do tag to say what will happen if u are walking past and i am hanging! will i live??
