My mother went on a business trip five months ago. Yesterday, my father had to pick her up and stay in a hotel. Did he deliberately not want to take me?

Because your parents want to be alone, you ask this question, which shows that you are still young. You should be happy. Your parents are very loving and your family is very happy. They didn't mean not to take you, but adults also need space. Many things can't be done at home. It is inconvenient to have you around. Besides, your parents haven't seen each other for so long. You really need some privacy, so don't get angry. Your parents love you very much. Don't be impatient. When this happens in the future, you should take the initiative to tell your father to pick up your mother and be sensible. Maybe you will have a younger brother and sister soon.
