People get freaked the hell out. They become defensive really quick.

It’s sort of become a game of chicken. It’s cool to say you want people to ask questions whenever they don’t understand something–the people that legitimately feel this way are exempt from this post–but way more often than anyone admits the asker doesn’t understand because the askee doesn’t either. Far too many conversations lately have gone like this…

Me: I don’t understand that, can you explain?
Someone: Ya know, something like xyz.
Me: I still don’t know what you mean. Can you give me an example?
Someone: [completely ignores request for example and uses the term "ya know" again]
Me: [slaps self in head]

The real frustrating thing here is that this only happens because people are lazy and try to give instructions without understanding the task themselves. This, of course, is a waste of time. Most often, you will get back a shitty (or maybe mediocre) product that isn’t really what you wanted. If you’re lucky, you’ll get asked enough questions to make it clear that whatever you were hoping would happen is a waste of time–if you’re really lucky, this will take less time than would have otherwise been wasted. Some of the time you’ll get back the same shitty product as in the first case, but you’ll still have through so little about what you actually wanted that you don’t realize it sucks. In this case you’re blissfully ignorant. Many would consider this the best possible outcome.
