If you know me you know that the number one way to break my heart is to say you are going to do something and then not do it. Don't make a promise that you may not live up to. Let your no be no and your yes be yes. I am currently sitting in a coffee shop reading a text book about Wisdom Literature from the Bible. The author is saying:
Some things are said in social contexts where everyone understands that these are not legitimate promises that people expect will be kept but sometimes other people take our promises seriously and our failure to do what we said we will do not only disappoints others but also undermines our credibility and our reputation as people of integrity. (Edward Curtis)
Really, if you don't mean it, don't say it. Don't tell me you're going to call or show up and then not. Could it be a scar left from years past? You bet, but whether it's a tick of mine or not it's rude, breaks truth and at times can be quite painful. The bottom line? Take it from Proverbs: Think before you speak.
