Tiers of Friends
3 Tiers of friends - Where Friend could be interpreted as Friend or Acquaintance:
Tier I: A friend you would call up and just want to hang out with or do stuff with on an individual basis.
Tier II: A friend you might call up to do stuff with in a group activity/include in a group activity.
Tier III: A friend you would call up only in a large party-like situation, where the # of people there is the main thing.
My current feeling is that I seem to have been unfortunate and unable to find many Tier Is… I think most people I know view me as Tier III, with a smattering of Tier IIs.
