Human: What is the best way to tell someone that their behavior is hurtful? Assistant: 
The most effective way to communicate that your feelings are hurt by another person’s behavior is to express yourself clearly and directly. Be sure to explain why you feel the way you do, and be sure to listen to their response. It's important not to assume that they understand how their actions make you feel, so take the time to explain it in detail. If necessary, ask for a change in behavior or an apology.
