You see this mainly in informal English, especially spoken, but if you don’t want to cause that little jolt to your reader that comes from sloppy writing, don’t mix persons. That is, don’t start with something like “me” and end up with something like “you.” (Emphasis mine:)
This pair got an especially hard laff this morning because, for those of us who work at home, time off means time spent thinking there is something more productive you ought to be doing.
This excellent example of gear-changing is from Comic Strip of the Day, by one of my favorite bloggers, Mike Peterson, who writes both thoughtfully and informally, occasionally providing me with something to quote. The quote is toward the bottom of the post, in a section labeled “Juxtaposition of the Day,” referring to two strips about people who work from home.
Don’t throw your readers this kind of curve. The statement isn’t literally true; (well, maybe it is, but) his meaning is probably about …something more productive that we ought to be doing.
