ADHD is a diagnoseable condition that has nothing to do with what you are trying to say. Break the stigma. I have loved ones with ADHD. It’s not the butt of a joke or something to call someone. People don’t make fun of people with anemia. This is no different. It’s a medical thing that the individual isn’t at fault for or has a choice in. If anything, a person with ADHD deserves understanding and patience.
