Chagrin is, in a sense, an ironic word. It derives in part from a word that means “rough skin,” but it expresses our level of “thin skin.” We let events or personal encounters break through, leaving a contusion on the soul.
We live in a world of sharp objects, so getting scraped or even deeply cut is inevitable. Generally, contusions heal, but some of us with thin skin get so deeply cut by the slightest bump that others have to tend the wound, even do some stitching.
Callouses are rough and tough skin. They develop from friction, giving once soft hands a new defensive barrier against future abrasions. Callouses indicate survival during past encounters with abrasive materials.
Want less emotional chagrin? Get some rough skin by handling the abrasiveness around you. You’ll better handle increasingly more abrasiveness by handling the rough stuff now. Thicker skin wards off future cuts.
