Hopefully. Respect.

Same to you. That was the first time I did it and I did feel bad afterwards.

I wouldn't feel bad. I'd send a message explaining the reason though, otherwise the message being sent wouldn't be fully understood. Positive reinforcement works usually, but with dense motherfukers you gotta explain it to them followed by a negative action. Due to their ego. My guess is what he was doing was trying to help in his own way, but has poor social skills. Due to that he came off as he did. It doesn't make it okay though haha, but they still need to learn the lesson. Which is not always a "kind" lesson.
