Walk to the Park.

You decide to spend a day at the park, as it's really nice out. You start walking, and you feel the fog weighing you down slightly as you walk, almost increasing as you go. You get there and relax on the bench for a bit, getting some water from a vending machine.

You jog around for a bit, admiring the blooming flowers. You chuckle at the chattering squirrels as they fight over a few seeds on the ground. After some time, you loop back around to the bench you were on earlier, and the fog comes in strong again.

You pause for a second when you reach the bench, unsure what to do as you see what's on there.
