“Every obnoxious act is a cry for help.” – Zig Ziglar
When a person is mean for no reason, its often a reflection of the pain they are experiencing in their own life. Try not to take it personal when someone like this lashes out at you. Instead, try to respond with compassion and whatever you do, don’t let it corrupt your good character. Remember, you can’t control a person’s actions but you CAN control your response. Your patience could help change their situation.
