I suddenly remember a cheater saying that, it doesn't matter if you are poor, but if you are poor in spirit and have no kind words for your wife and S/O, and a Mexican comes along and tells her how beautiful she is, you will lose. Therefore always have kind words for your wife and S/O, even when you have nothing or is already irritated by the situation. Kind words will save you from making a situation worse and losing someone who will only use them temporarily.
