What should I do if men keep harassing my wife?

If a man harasses your wife, you can warn him not to harass your wife, or you will teach him a lesson. I suggest you keep your wife away from his sight and don't give him a chance to harass. If he is still harassing, I suggest calling the police. This is a threat to others' personal safety and will scare your wife. The police will get even with him and warn him, so he won't dare. I hope I can help you and wish you a happy life!
