Replying is an important communication skill in interpersonal communication and a skill for success in society.
If you can't reply, the situation will be awkward and the relationship will become rigid. How to reply is more important than how to speak.
Being good at answering questions will make you popular and win opportunities. If you don't respond well, you will be rejected and miss opportunities. Replying is a knowledge and a technology. Replying not only reflects a person's oral expression ability, but also demonstrates a person's flexible argumentation wisdom and rebuttal skills.
