Me: *submits design document to manager, who sends it to client for review*

Client: "everything is good, except one line here mentions a function that has since been removed" *send email to manager*

Manager: Correct this one line *sends email to me*

Me: uh, ok *deletes line, sends updated document in new email*

Is there any reason in the world the client OR manager couldn't have corrected the line and moved on?

Did we need to get two more people involved and send 3 more emails?
