Questions about the riskiness of specific situations are the most difficult to answer. These situations often include a lot of details… and a lot of unknowns. There are so many factors to think about all at once: individual health history, your behaviors related to COVID risks, everyone else’s behaviors related to COVID risks, the specific arrangement of the event, the expectations of people you care about, etc. It’s impossible to try to hold it all at once. We get it.
You cannot assess the risks of every single situation–no one can. But you can consider your comfort and how you can reduce your risk: ask yourself what the worst outcome is, and do what you can to guard against that–no matter how unlikely the worst outcome may be. Once you’ve made those assumptions, things may become much more clear. What can you do to reduce the risk of that worst case outcome? That’s the only variable in your control, so control it!
