Some people are ready for things like handshakes and hugs again, and some aren't. So how do you tell? Well, here's one idea . . .
A lot of conferences have started using colored WRISTBANDS as a way for people to know who's okay with physical contact, and who isn't. Red means stay six feet away . . . yellow means touching elbows is okay . . . and green means you're okay with things like handshakes, high-fives, and hugs again.
It's not a new idea. A company called Social Bands started selling the wristbands last year. But "The Wall Street Journal" just did a big story on it this week. And they're becoming more popular at big social events, like weddings.
