dead friends

People you are friends with only because you we're forced together for a long period of time. (i.e in a classroom or work space) You find them unreliable, they don't KNOW you, you don't know them even after all this time. You're personalities don't match yet you hang out and can talk with each other. If follows the "Friends you realize you were only friends with because you saw them 5 days a week” mentality.
