If we're taking one characteristic of a person and applying it to the whole person, we're 🏷 Labeling. If someone brushed us off, they might not be a "jerk," maybe they're just in a hurry. This applies to ourselves as well; just because we make a mistake doesn't mean we're a "failure."
I failed a test, so I'm a bad student.
Labeling can often come from ✨ Should Statements, since often when we think someone should be a certain way, we're also labeling them.
