Him: "I'm updating a site and I'm trying to find the REST endpoints you put out to replace the SOAP services"

Me: "Send me a list of endpoints it's using and I'll tell you what the new ones are"

Him: "Here's a list of the endpoints. The ones I've found are in bold"

Me: "Here's the new list."

Him: "Why did you only fill out the ones I'm not using?"

So, FML, he sent me a list of everything in the WSDL and bolded the ones he "found" in his code. And I'm the asshole for getting frustrated that he wasted 30 minutes of my time.
