I'm sorry to hear that you and your mate got into a physical altercation. It sounds like things got out of hand during your play and resulted in unintended harm. When someone gets hurt and starts crying, it's often because they are experiencing physical pain and emotional distress.
In the situation you described, it's crucial to acknowledge the gravity of the incident and the impact it had on both of you. Physical violence, even if unintended, can cause harm and damage trust in a relationship. It's essential to communicate openly and honestly with your mate about what happened, express genuine remorse for your actions, and discuss ways to avoid such incidents in the future.
Remember, physical violence is not an appropriate way to handle conflicts or disagreements, even in playful situations. If you find that you or your mate have difficulty controlling your actions during play or other interactions, it might be helpful to seek guidance from a counselor or therapist to learn healthier ways of expressing yourselves and resolving conflicts. Respect and empathy are crucial for maintaining healthy relationships with those we care about.
