You’ve received a holiday gift through the mail — a common enough scenario during a pandemic when meeting face-to-face is, in many cases, not an option. You open the package and see a thoughtful present inside. But something’s wrong. You search the box several times, but it’s just not there — the gift note saying who sent it. We admit, considering what else is going on in the world, this is a pretty low-level crisis. But it can be awkward. Do you text a few people and ask if they sent it? They may feel bad about not sending a gift if they didn't. Is a phone call more polite? Do you post it on social media for everyone to see?
