Me: junior dev

Assignment: build a REST search service that also does (thing x)

Me: gosh I just can't figure out how to make (thing x) work! Nothing I try works and there are no online resources!

Me: awesome! I think I can build that

Manager who can't code: what are you talking about, (thing x) is clearly better and it should be possible to do

Manager: *sends email outlining shifted requirements after the meeting, including (thing x)*
