@jamey This relates to my pet peeve of, when explaining a problem I have with, say, the company network and how it interferes with my workflow, one of my coworkers will enter the conversation with "Why don't you just <do something I tried and rejected weeks ago>?"
The way that sentence is worded makes the (wrong) solution sound trivial and obvious, so it is actually a little insulting to the intelligence of the person it's said to. A simple "Have you considered <thing>?" works just as well.
