Here's a true story from a residential community: a couple, the man works hard at his job,

the woman stays at home browsing the internet and chatting,
they talked about investing, then arranged to meet in person, and everything was happy,
after leaving the hotel, the online friend said he wanted to buy her an electric bike, and the woman felt a bit embarrassed to ask for a good one,
the online friend was generous—if you're going to buy, buy the best—she looked at one over 5,000, and after it was installed, the online friend said, "Let me try it," and as a result, he rode off and never came back...
Later, her husband came and paid the money, and this is our famous electric bike incident.
