It's never okay to steal things from people
Rachel is at her friend Marti's house  and really likes her earrings laying on the table.
Rachel wants to wear the jewelry.
Rachel tells Marti that the earrings are lovely and asks if she can borrow them.
Rachel sees that Marti isn't looking in her direction, so she takes the Earrings and puts them on when she gets home.
Marti agrees to Rachel's request and the two friends bond over having similar taste.
Marti realizes that Rachel stole from her and calls her to end the friendship, so now Rachel is sad.
