It's inevitable that we'll wrong someone at some point. We'll say the wrong thing, react with anger, or hurt someone's feelings.
When it happens, how we handle it matters.
The best way is with an apology.
A heartfelt apology can go a long way toward restoring the relationship. Unfortunately, many times apologies are muddled by one word: but.
When apologizing, it's important to allow the apology to stand alone.
"I'm sorry" should be the full statement. It shouldn't be "I'm sorry, but..."
When it's followed by the word "but" the apology is diminished. Adding "but" adds an excuse or tries to place blame elsewhere. Instead of adding "but," just take full responsibility. Be humble enough to simply say, "I'm sorry."
That one simple statement means everything.
