Saying “I told you so” might get your point across. It might prove you were right and someone else was wrong. It might give you some status…for a moment.
You might feel like you win (and someone else loses, and you’re okay with both). But in reality, “I told you so” is boasting. It drives a wedge between people.
So what if you told someone something and they have now learned the hard way? Isn’t learning the hard way enough? What if, instead of kicking them while they’re down, you reached out a hand of encouragement, helped them dust off, then offered to walk the next few steps together as they limp?
Of course, sometimes staying alongside someone isn’t the most healthy option for either you or the other person. You need to walk separate paths for a while. And if you’re walking separate paths, there’s still no need to say, “I told you so.”
Let them realize it in their own timing. It will stick longer, and you’ll maintain some respect for yourself, and potentially from the other person. After all, would you continually go to someone for advice and help if they constantly remind you how smart they are?
You don’t have all the answers. None of us do. Let’s be humble with what we do know, be willing to grow and change as we discover our misunderstandings, and respect others every step of the way.
