Dear Lei Zhang of Fujian Nan’an Boreway Machinery Co., Ltd. in Shuitou Town, Nan’an City, Fujian Province, China. We have never met. But you emailed me on my blog email this morning. Your email was beautiful. I sadly have no use for boring and grinding heads as I sadly have no boring or grinding equipment. I wish I did. I saw the attached photograph of bush hammer rollers and thought to myself, “This is good and useful spam. All spam should be this good and useful. Imagine if it was, I would buy things.” So, thank you, Lei Zhang, you have done the unique. In all my years of receiving spam, in all those tens or hundreds of thousands of impersonal and unwanted emails, yours is the first that’s made me say, “I wish I had a need for this, I would buy immediately.” It’s true, if I had spare cash, I’d buy some bush hammer rollers just because they look brilliant — and I’ve never even seen them before. Because of your email, I learned something new, which is what is best in life. You must think I’m being sarcastic and mocking you, but I’m not. Yours is genuinely the best unsolicited email I’ve ever received.
