Who's in your fave five? Well, if you have a new flame, two of your besties aren't.
Researchers at Oxford University have found that most of us tend to have an intimate circle of four or five buddies. When we embark on a new relationship, we end up dumping two of those close friends since we no longer have the time to focus our attention on them.

Children, pets, Don Draper and inanimate objects can also take up space in those five friendship slots. Wait, we're a little confused -- if you're married with three kids and a dog, does that mean you have no friends?
Just in case you were wondering, men are just as likely to choose to ditch their pals for their gals. Which is marginally refreshing, given the previously insurmountable bros-hos doctrine.
