First: mobile phone computer. Because both mobile phones and computers may have their own privacy, if the other party sees some of your privacy, you are not wrong, but you will think in the other party's mind. This is the private space that every adult needs. It's not a question of whether it will be hidden, but to reduce some unnecessary troubles and make feelings less likely to be hurt by irrelevant things.
Second: credit card. If the husband and wife share the same credit card, there will be unclear consumption details. There may even be cases where one party ignores the credit problem of the other party and only meets its own needs without considering the consequences, which will easily lead to the breakdown of feelings.
Third: toothbrush. No matter how loving the relationship between husband and wife is, you must use your own toothbrush. If you want to express the love between two people through the habits of daily life, then two people can choose to use a couple's toothbrush and a couple's tooth cup, which will be sweeter than sharing a toothbrush. It's not that two people dislike each other instead of sharing a toothbrush. Just from the health point of view, sharing a toothbrush is a health hazard.
Therefore, if the feelings between husband and wife want to keep fresh all the time, they need to give both sides some space.
