You know the stickers on the floor near the check-outs at a store? The ones that show a pair of feet indicating "6' social distancing?"in the lineup? I confess that when COVID finally eases off I hope those stickers stay. It took a pandemic for some people to get the drift that personal space is actually a thing. Remember when someone in a huge rush, with no self awareness at all, would just hang on the back of your shoulders breathing down your neck as if that makes the line go any faster or the cashier's fingers fly any quicker on the cash register. I always wanted to say "back the F up please" but thanks to the pandemic, I'll just politely glance at the sticker and then at them, and glance at the sticker and back to them. And smile. So much more civilized.
