Two Different Elevations

The sun is setting and the shadow from the curb near the intersection of 22nd and Nueces is getting longer and more faint. There are a lot of cars on the road now and there's a good amount of activity going on in this area. A blue Jetta parks on Nueces and a woman and her young daughter get out of the car. The daughter probably just recently graduated from the "my mom carries me everywhere" age to the "I walk with my mom" age, and they walked side by side down the sidewalk holding hands. When the young girl got to the step, which was fairly high up for her, her mom reacted by lifting the girl by her arms up the step. She lifted her quickly, and a bit higher than necessary to give the girl the feeling she was jumping high.

It's getting dark out and a group of five of what appears to be college-age guys heading towards campus, talking as they go. They are standing side by side in a line, so that 2 of them have to walk in the grass on beside the road, 2 are on the sidewalk, and one is on the grass on the other side of the sidewalk. As they cross the driveway approaching the curb, the guys walking on the grass fall back and step up where the sidewalk is instead of stepping up where the grass is.

It's 7:30 at night and now this sidewalk isn't very well-lit. A man dressed in khaki pants and a burnt-orange polo shirt crosses the street and continues walking on the sidewalk. His eyes are locked in the distance, it seems like he's staring at a car. As he gets closer to the fairly tall curb, his gaze shifts to the step down ahead of him. He slows a bit, maybe to time his step right for the curb. The step down is smooth and the man continues towards his car.
