Happy Birthday<br>Heathers mom's birthday is today. Heather waited until the last minute. She waited so long to get something she almost forgot. Heather went to the store looking around. She decided to get a bouquet of flowers for her mother.
Heather's mom bought a bouquet of flowers.
It's definitely incorrect because Heather bought the flowers, not Heather's mom. It's difficult because the sentence contains many words from the text and it's structured very similarly too.
