A true friend who will be there for you till the end. Sure sometimes there will be a fight between you and this person, but deep down inside this person truly does care for you. This is a person that will give you car rides home as well as any other favor for you (sexual, but not all the time). Towards the end of the day you will not be able to not think about this guy due to all the nice things he has done and the memories that will last a lifetime.
You are such a David Withrow, I love you man!
