Happy Chinese Lunar New Year

Got home and saw my mom.
She is getting fat. I guess it's a good sign.
Since people are getting together and having fun today, I hope I can offer some happiness as well.
It's a joke that my mom made.
One day, my mom called me and said there was a letter addressed to me.
I asked her to mail it to Taichung for me.
Then, couple of days later, I got a mail, but it was not addressed to me.
You see, my family name is "Chen."
And my mom's is "Drun"!
Ok, but the letter is addressed to "Lin XX"!
I recognised my mom's handwriting so I knew that was for me.

Ridiculous!I felt funny but anxious at that moment.
I called my mom immediately.
"Mom, I have already grown up. Now you can tell me......Who is my father?"
.........................................................
Of course, I don't have another father!!

The joke tells me that my mom is getting old.
