As you go around the world, there are various ways in which we can say hello to one another. The handshake, the nose rubbing, air kisses on the cheeks—they are all things that we will be familiar with.

But just be thankful for one moment that you are not a member of another species of the animal kingdom, the white-faced capuchin monkey to be precise.

You see, when two of them meet one another, they have a very peculiar way of saying hello, and it is something that is not replicated anywhere else in the animal world. They say hello by sticking their fingers up the nostrils of the other monkey.

Yep, you read that correct. They stick their fingers up the nostrils of the other monkey.

Now, can you imagine us doing that when we see someone and want to say hello? Well, it could perhaps be worse.
