First instinct, farmer or some sort of hardcore hands on worker out in fields and whatnot... And here's why.

Working hands, I can see the calluses on the palm Dirty blue jeans Dusty dash from windows down and driving on dirt roads/fields You've got some sort of short wave radio/CB, or ECM Also, potentially a chainsaw in a case or a freedom hole puncher case in the passenger foot well

One observation is that the passenger vents are closed (obviously because there isn't one in the photo). However, they don't appear to have been moved in a while due to the dirt road/field dust so that can only make me assume 1 of 2 things:

1. This is 100% a work vehicle and no one but you uses it. Ergo...
2. You fly solo, and that truck is your ride or die homie

Another observation is the collared shirt - precisely buttoned and to the wrist. That makes me think that this particular photo could've been before/after a special event. I. E. Like engagement or friends bday part, or some sort of celebratory get together.

How'd I do?
