Someone asked what's the most important part of the body. A doctor answered 'The brain' and a drunkard said 'The shoulder'. They were forced to ask why, he said A friend in pain is a friend in need. They said what does it have to do with anything',he asked have u ever cried on a shoulder?,is full of hope*sigh*.Nevertheless,the shoulder supports the hand which reaches many aids like surgery,money exchange,shooting,drinking,clapping,slapping...and so on. How important it is, is how available it can bé when you need it.
