It is terrible to steal from a friend.
Kerri is ad her friend Jodi's and Jodi shows her a necklace that her mom bought for her birthday.
Kerri wants to wear the necklace.
Kerri asks Jodi if she can try on the necklace and after doing so, asks to borrow it.
Kerri waits until Jodi puts the necklace away and sticks it in her pocket when she's not looking and wears it when she leaves.
Jodi appreciates being asked and lends it to Kerry who is very pleased.
Jodi notices the necklace is gone and knows it was Kerri and now no longer wants to be friends.
