Lunch Confusion

Working from home makes meal times just flexible enough to cause all kinds of confusion. At what point have I missed lunch? I mean, if it's after three and before six... is it still lunch? Or do we need a new word, like lunner? Dunch is more fun, but since dinner comes after lunch, I don't think it works.

And if you work in an office, just how late is too late to go to lunch? I mean, at what point does your boss just say "To bad. So sad. No soup for you!"?
