We have seen it before in many a con, good manners outshines capabilities so often. If people are well-mannered/polite, they are considered more intelligent, more personable, of higher caliber, better trusted, even if those things are not true. This is especially true if good manners are accompanied by good looks. And we see this play out everywhere. People buy it.
And on the bad side, that is silly not to dig deeper to the beliefs of a person and their actions and just buy their wares.
But on the good side, if we always respond with good manners and teach our children to do so also, we/they will be better thought of, will stand out, will be considered suited for better jobs. Manners matter.
So the point is to use good manners as often as possible and teach your children to do so also. And on the other side of the equation, look beyond manners at actions to see the heart of a person. This way we are being the best we can be in every situation. It is part of good stewardship, which God requires. We must be appreciative and wise with what He has given us.😄❤
