Friendly suggestion since the monkey said to be polite: if you’re out with your wife and kids and encounter a mentally ill homeless person who makes a rude comment, just keep walking. Stopping to trade verbal barbs is not protecting your family. Every fight you avoid, ESPECIALLY in the presence of your wife and kids is a fight won. What possible good could have come from prolonging an encounter with a mentally ill homeless person? I truly hope that story was just internet talk and you don’t actually make poor decisions like that in real life. If so, find a training class on MUC.Once the threat of a deadly weapon is added to the situation all thoughts of a fistfight are off. Especially in the presence of the most valuable thing I have. That being my wife and kids. At that point I will do all I can to ensure that the threat does not outlive me. Insinuating that I am somehow less of a man because I did not try to fight a mentally ill homeless guy with a knife well that’s just ********.
