"How'd it work out?"
It turns out that the light fixtures a builder used in my kitchen a few years ago have all begun to fail. One by one, each one stops working.
My guess is that he has no idea, and continues to confidently install these fixtures, his go-to choice for kitchen lighting. And why not? He doesn't know that they only have a relatively short life. He doesn't know because he didn't ask.
Doctors and consultants and builders are often hesitant to ask about how something worked long after the work is done. It feels like nothing but a chance to hear a complaint.
It's not. It's a chance to show that you care. And a chance to learn how to get even better at what you do.
