You have many things going on here.   
You have the curves of the peel.
The oxidation of the inner pulp.
Negative space gives us a sense of isolation and alone.

I saw this on a walk between my favorite park and a school.   Most likely dropped by a student.  This was just a few days after the schools went on extended leave and a few days before the Ohio Stay-At-Homer order due to COVID-19.
​I'm sure I need not say much more about it, you can infer quite a bit from the scene.  Draw your own conclusions.

GESTURE
This study gives us 2 subjects.  Taken out of context we could interpret this as one person is more interested in their phone than the person with them, and the other person is tired of being ignored.
Yet another interpretation could be that the person to frame left is looking for something to share on their phone with their counterpart.   Person to frame right could have a headache, be tired or just finds this a naturally comfortable position to rest at the moment.

MORE DETAIL
Camping out at the Roosevelt Coffee Roasters on Broad Street in downtown Columbus Ohio provided for some interesting people watching.   This image was captured in mid January, where the Ohio winters can be brutally cold.   On this day the high temperature hit only 21F and it finally stopped raining, but a small snow flurry would peak its head in from time to time.

Truth is on this scene that the 2 people in question were sharing a friendly conversation and sharing stories, some of which were supported by images from the one mans phone.

GESTURE
Images can be layered and often gesture can be found in not only the human element but also in the inanimate.  In this image, one could argue that the non human elements gesture could dominate over the human one.

Starting with the humans, they are not together.  This is implicated in the obvious, they are not engaging each other in any way and have quite a bit of distance apart from one another.  The not so obvious play is the disconnect in their direction of view.   Not looking in the same direction can cause you to immediately have a feeling of disconnection between them.

Moving on to the seating, we have a gesture in them and how they are arranged.  You get a sense that they are made and positioned in such a way that the intent of them is to have those that occupy the seats are to commune together.

This could be a strange implication given the often apparent disconnect technology can place on those immediately around us in the 21st century.
The seats do have an interesting symmetry to them as well.

MORE DETAIL
The Columbus Metropolitan Library - Main Branch is a frequented building.  Not only for the books we find inside, but for the grand architectural achievement and community it provides.

Colors here played no real role in the telling of this scene, so were abandoned for the monochrome treatment you see here before you.
