One of the strangest things I ever observed in what I think was a Sensing type, was when he was trying to build something out of copper tubing, and he wanted to put sand into it so it would bend without "kinking" or something. He purchased sand with rocks in it, and I told him "Why don't you filter the rocks out?" He said he didn't have time to do that. So he tries to force the sand, with the rocks, into the tube with a wooden stick. So a couple moments later, after trying to figure out in my head why it wouldn't work and not finding any reason, I say, "I still don't see why you don't just use that mosquito net over there, put a bowl under it, and pour the sand on top of it?" He slapped himself on the forehead and said, "Why didn't you tell me that sooner?" I said, "I thought I did. I just assumed you had already run through the idea, and dismissed it because it wouldn't work." He said, "No, I just didn't see what you meant."
The thing is, this person was always working with tools, and I assumed he'd understand things like that easily. But I still had to point this out to him, and it was obvious to me, even though I'm terrible at using tools. Why did it work out that way, especially since I've found that Sensing types are usually better at dealing with practical problems? The whole thing really seems strange, now that I think about it.
