Dad is having an affair. Today is Valentine's Day, but he hasn't come home yet.

People like your parents are most likely to have extramarital affairs. A man doesn't have to argue with them for the sake of taking part in accidental amusement, but if he is serious, it will be a little troublesome. I hope you can communicate with your father and understand why he did it. There are usually two reasons. One is that he has been married for a long time, and he has lost his enthusiasm for your mother at first. The other is that he wants to stimulate himself to meet his own requirements. But usually they will find that if your father is here, his wife will swear that she is not here.
