When you find yourself wanting to express an opinion about another person’s actions, ask yourself: Are you their keeper?
Is it your job to tell them what to do? Are you responsible for them?
No.
You just want to be right. You just want to help.
You can help by letting them sort out their own affairs. If they need more help than that, they’ll ask.
Don’t give unsolicited advice, no matter how badly you want to or how helpful you think it will be. Are you their keeper? No? Then don’t act like it.
