You Are So Not Invited to My Bat Mitzvah!

Stacy stopped speaking to Lydia after discovering that Lydia and Andy had started dating. The timing felt like a betrayal to Stacy, especially since Lydia had helped announce that Stacy's crush on Andy was over right after the humiliating maxi-pad incident at the ledge. Stacy felt hurt and isolated from her best friend.

The entrance video Stacy created for Lydia's bat mitzvah contained unflattering and embarrassing clips of Lydia.

During a day out at Kym Chang Cohen's house, Stacy jumped off a high ledge into the water to impress her crush Andy.

Stacy had numerous arguments with her parents Bree and Danny over the bat mitzvah's attractions and her wardrobe choices.

Her parents had their own ideas about what constituted a proper celebration, creating ongoing family tension.
