What greetings should we use instead of shaking hands?

Booty bumps! 😆

There was a great cartoon in the British satirical magazine [i]Private Eye[/i] of two people knocking elbows. The caption was something like: 'Sudden outbreak of Elbola.' 😀

Crotch grab.

Let’s be like in Demolition Man and just say salutations

A quick bow at a respectful distance?

Maybe like the Germans did ,seems to have worked

slight bow--Japanese style

Just saying hello would suffice. I still say "Hello Eddie" to every pigeon I see but I never shake hands with pigeons, ever.

Has together as in prayer and bow.

Air high fives.

Butt bump.

Fist bump 👊

Waves perhaps

🙏Namaste

Namasta 🙏🏼🙏🏼
