The Lord Giveth, and the Lord Taketh Away

Tacky girl #1: Why do I feel like every time I gain a friend, I lose a friend?
Tacky girl #2: (silence)
Tacky girl #1: It's like AIM buddy lists, like when you max, you know? You have to delete a friend to add a new one, you know? My friendships are all like that, you know?
Tacky girl #2: I don't think it works like that.
Tacky girl #1: Yeah, you're right.
Tacky girl #2: Well, if it was like that, who would decide?
Tacky girl #1: Umm…god?
Tacky girl #2: Well, maybe whoever's deciding is telling you to look at the friends you do have, and, like, see if they're worth it.
Tacky girl #1: Ohmigod! You are so good. How did you get so good?
