Paternity Tester, Is Your Child Biological?

[Diary of a paternity tester who has been practicing for five years. Industry knowledge. The mirror of humanity. That toothbrush costs more than $8,000. Sent whole. After the test, it was not her husband's. She said, "Okay, I'll send another one." Another test was taken. Not yet. I didn't get it right until I measured the fifth one. That cigarette butt costs twenty dollars. No brand. Extremely ordinary. The first four are all in vain. Five men and one pregnant woman. When she got the report, she said, "It's finally right." His tone was as light as buying a discounted piece of clothing. I have been doing paternity testing for five years, and the most outrageous sample I have ever seen was a clump of cat hair. The postscript read: "Let's see if the baby is mine." I took a look at it through a microscope and it was cat hair. If you've been in this business for a long time, you'll never guess what's in the next package. You can never guess what the expression of the person opposite will be after a report is handed over. Some people cried on the spot. Someone laughed. Someone was silent for half an hour. Someone squatted in the corridor and sat there from afternoon to ten o'clock in the evening. I'm not a demolisher. I'm just the one looking at the answers for them. What is written in this book is all the truth. Do you dare to look at it?
