Why does sand stick to everything even though it doesn’t feel sticky?

The Short Answer
Sand sticks to things in many ways just like flour does. Flour particles aren't sticky at all (while dry), but small enough to be caught in tangles of fabric fibers, attracted by even the slightest charges, or "grabbed" by microscopic droplets of water or oil (and the human body is literally covered with oil-drop and water-drop emitting organelles: sweat glands and sebaceous glands). Flour is many times smaller, so more sticks of course, but at the size level of a grain of sand a human body is covered in a rough shag of fibers, and sticky oil and water films. None of these hold on very tightly, but tight enough to resist gravity and most movement, so the sand doesn't just fall off when you stand up. Brushing the area is more forceful, and tends to knock off every grain of sand hit – but again, sand is so small it can "hide" in the fabric or get missed by a rough hand brushing.
