While we were going about our business on Monday, March 22, 2021, at 2:30pm, a gunman entered a grocery store in Boulder, Colorado and killed ten people. He used an automatic rifle that, as was later discovered, was purchased legally. That grocery store was seven miles from our front door. The echoing trauma from that singular event—representing countless others—is immeasurable. We told our 11-year-old daughter, Opal, the following morning.
