What should I do if I forget to pay New Year greetings to my girlfriend's parents?

Apologize to your girlfriend quickly. No matter what she says about you, don't talk back. After all, you are wrong.

When she has finished venting, you can ask her parents what they like, buy something, or make a phone call to celebrate her old age.

When you go or make a phone call, don't make excuses to cover up your forgetfulness. Parents are more experienced than you. Don't show off your cleverness in front of them and say goodbye to your old age politely.
