The pull request with all the code.

this can all be extracted out into something like this:
``` ruby
def show
  user = find_user
  if current_user.friends_with?(user)
    @currently_friends = true
  else
    @currently_friends = false
  end
end
```

I don't really like that we are just setting a boolean here... you could just place the `current_user.friends_with(user)` conditional in the view using an instance variable and it would look much cleaner.
