We have very rarely worn masks since those mandates all went away in Ohio. Have been living life pretty much like pre-pandemic for quite some time. Exception being during the big Omicron spike over the winter. A lot of friends we hang out with are doctors and we have modeled a lot of our habits based on how they are handling it.

Maybe when she was out shopping with friends or out to lunch? Nothing egregious I could point to though. Seems like the current strain is so contagious that it will be difficult to avoid.
