"Mengmeng, how can you be so naive? Your husband doesn't have a tumor, that's a part of a boy's body, just like us girls have our special areas..." Gu's mom babbled on and on, probably because she's a doctor. Once she started, there was no stopping her, and she ended up giving Mengmeng a heap of knowledge that a child should know.
Many people are hesitant to share this knowledge with children, thinking it's something filthy, but they don't realize that the more children know, the more they understand its importance, learn to protect themselves, and reject evil touches.
"So that's what it is!"
Luo Mengmeng's curiosity was finally satisfied.
You see, that's how children are. If you keep something from them, they tend to dig deeper, but once you explain it clearly, they find it uninteresting.
However, this also made Gu's mom realize that her son and daughter-in-law had really grown up without her noticing, and it seems that she could no longer let them bathe together anymore.
