In the city of Los Angeles, where I live, you can't enter a restaurant, a government building, a gym, a bar, or a coffee shop without showing proof of vaccination. I know some establishments are less apt to check than others, but each time I walk past a "no vaccination, no service" sign, my heart skips a beat.
The few times I've entered a restaurant lately, I've joyfully whipped out my proof-of-vaccination card. I enjoy doing my part. Getting vaccinated against COVID-19 is not any kind of sacrifice.
It is an act that is, paradoxically, both selfish and selfless.
