well, my fingers are very sensitive to tiny texture differences between materials. Different paints on a wall, different plastics and wood coatings, screens, various object materials, dirty-or-clean surfaces, oiliness, roughness, etc. and the fine touch can create a cascade in my head _somehow_ that can be a magical sensation that I can’t describe.
