Early<br>Tina wanted to spend more time with her mom. So when her mom invited her to go out one morning, Tina agreed. They left at 9 AM and went to several garage sales. Tina had hated getting up so early. But she loved spending time with her mother!
tina's parent invited her to go shopping.
Tina's mom is definitely her parents and she wanted to go shopping with her mom. i think the system didn't understand that tina's mom was her parent.
