In the end, Sarah decided to accept Arthur's invitation to lunch.
She didn't know where Michael was taking her children because she forgot to ask, but Sarah was sure he wasn't taking them straight back to the apartment.
That means, she will only be alone in the apartment.
So with that in mind, Sarah felt there was nothing wrong with her accepting her childhood friend's offer.
Not long after, Sarah and Arthur were sitting at one of the restaurant tables near the law firm where Arthur worked.
"But I never thought I'd see you again!" said Sarah after the waiter had left with their order. Her facial expression looked happy.
"I know, right? It's been about twenty years," Arthur said with a smile and moved his body forward while supporting his head.
"But how can you recognize me? Do I still look like I did twenty years ago?" asked Sarah who looked confused and amazed that Arthur could still recognize her.
