You may have heard that we have a pretty good women’s gymnastics team, and I am here to report: This is accurate. The first day was not without heart-in-your-throat moments, including Simone Biles’s tightly wrapped calf — whenever that woman winces, it’s like a butterfly flapping its wings and causing a tornado — but it also had stunning acrobatics and some damn fine costumes. The top 8 teams will compete on Tuesday. I’m biting my nails in advance.
