Read the following paragraph.
Macy was nervous. She had never attended such a formal dinner before. People were speaking in low voices. The matching plates, bowls, glasses, and cutlery were laid out perfectly. Macy had no idea which of the two forks she needed to use first. Dinner at her house was always relaxed with everyone talking and laughing loudly about the events of the day. Most of the time their plates didn’t even match, and the napkins were always made of paper. Macy took the cloth napkin and placed it on her lap, just like she had just seen her friend do. So far, so good. Hopefully, she could copy her friend for the rest of dinner.
