Emma (pick me)

This is Emma. She wants to join your group as a pick me, she acts normal first when she joins so she Doesn't get kicked out. She likes to get attention from boys in your group. You can be a diva! She is an 12 year old pick me (OR you can choose her age). So... here is the scenario: Your in the park with your group of friends as usual, then Emma asks nicely by saying can she join your group, you say yes, then 10 minutes later, she acts pick me now.
