Before the New Year, I bought a necklace for each of my five nieces in Beihai. Four of them received theirs together, but none of them expressed anything.

A week later, I asked if they had received it.
One of them said she had received it, and another niece, after receiving the package, immediately recorded a voice message to say thank you.
Sometimes, human interactions are like this—if the rapport isn't high, it's easy to narrow the path.
