English translation, put an end to machine translation, 10 minutes will get extra points!

This passage should be about Christmas, when families give gifts to each other early in the morning. The following is translation, which is more colloquial, without paying too much attention to the beauty of language:

I was particularly shocked. "I want a piano, and then I can take piano lessons" has been a joke in our family for a long time. Every time my husband's answer is "you learn the piano first, and then I'll buy it for you."

I stood there in tears and kept asking my son how he could afford such an expensive gift.

Of course, when my family woke up, my son was very excited about my reaction. I kissed him many times and immediately asked him to open the present I gave him.

When he saw the helmet and all the equipment, the expression on his face was not what I expected. I immediately realized that he had sold his motorcycle and bought me a piano.

Of course, I was the proudest mother in the world that day, and I was still on cloud nine for the next month.

So I think you know that in this ever-changing world, that kind of love (affection) still exists in my heart.
