"Is this a... Greeting?"

This body stood in the shallow waters, gazing at its reflection.

Any other being would have been content with a second's glance.

I wasn't.

I still did not understand this body, this place, and these other beings apparently equivalent to my current state.

I heard a cry, young and yearning, more than loud enough for the distance between its source and the intended target.

Me.

The cry was familiar, yet most things were. A distant familiarity that the simple, physical mind I now had could not grasp.

This body's head moved itself to face the crying one.

A fawn.

I felt my body react. I could feel it wanting to move away, but I stopped it. I am still not sure why.

The fawn stepped out with one leg and lowered the front of its body toward it. A bow, as it is known.

I did not understand at first. What did this gesture mean?

This body must have made a curious motion, since the fawn repeated its gesture and nodded.

I thought the nod indicated an emphasis of some sort. An affirmation?

This body attempted to copy the fawn's movement.

The fawn nodded vigorously for what seemed like a long time, its eyes brightening as it... Smiled.

After more nodding and a bow, it went away.

So this is how this world's residents recognize each other's presence.
