Sean Adcock builds dry stone walls for a living. He is damn good at what he does. In fact he’s probably the best waller I know. Working along side him on a project, could be very intimidating but it isn’t.
The thing is, it would be very easy for him to say disparaging things about your work, or thoughtlessly point out things your doing wrong all day. But Sean, who is often grumpy and seemingly unfriendly most of the time, is surprisingly delightfully tactful when the occasion calls for it.
Now and then when it’s needed, he’ll show up almost magically beside you, just after you’ve put what you thought was a harmlessly iffy stone in the wall and say ”I don't think you're going to like that one later”. He’s usually always right. But he’s given you the credit that you’d know you will have noticed it eventually. Can you see something that the person who built this wall might have come to not like later, in the photo above?
