What is love?

I wrote this a few years ago.. but the blog that I am going to write made me think of it, so I thought I would post it.. 

Some say..  "To be brave is to love unconditionally without expecting anything in return to just give.."  But I wonder what is love? ... is it friendship,  is it trust that we place in another, is it an absolute rush of emotion...is it wanting to be near someone so bad that it hurts when you are not with them, is it a choice, is it missing someone when you have only just left their side, is it a willingness to cause ourselves discomfort in order to make another person happy and hoping that they will do the same in return, is it a willingness to give all of yourself to another only to have them give themselves back to you in return, is it a risk that we take... is it all of these things?

  To Love...is to be brave
