How can I tell my daughter-in-law if I don't go home for dinner during the New Year?

If you don't go home for dinner, you really have to explain the situation to your wife. What is the reason for not going home for dinner?

Make it clear. Don't let your wife misunderstand you. Be sure to tell your wife the truth. Otherwise my wife may not forgive you.

If you are with a female classmate or other female friends, you should also explain it to your wife. Otherwise, if she finds out later, there may be more misunderstandings.
