Losing a love one from death is no excuse to be an asshole.

Sorry if it sounds cruel but grieving doesn’t give you a free pass of being rude or being an asshole.

I have a guy friend that lost his younger sister last year and we have given him excuses for acting out but he would cuss at people and be rude. He called him out for his rudeness and told him to get out if he’s going to be an asshole. Look I am very sorry for his loss but it doesn’t excuse him for being a jerk.
I empathize with him and I understand he’s still grieving but being rude to people for no reason isn’t an excuse.
